After just coming back from a 10 day vacation, I was able to achieve voting reqs in less than one day (around 12 hours to be exact) with a very nice w/l ratio and got #12 on the suspect ladder. In my opinion, Greninja is a top tier threat especially for offensive teams, but I'd still have to say to
NOT BAN greninja.
In all honesty, I like Greninja's impact on the metagame. Pre ORAS, near the end of XY, the best playstyle by far was balance by a large margin. The ladder and tour battles alike were both infested with balance vs balance games, and both full HO and full heavy stall were pretty rare in the metagame. The "we should strive to create a metagame in which all playstyles are equally viable, like in late XY" statement is incredibly false because everyone and their mother knows this isnt true. Not all playstyles were equally viable in late XY, because balance was way more common and dominant than stall and offense combined. Now enter ORAS, and with the introduction of new powerful + bulky megas, and the improvement of Greninja's expansive movepool, the metagame has shifted away from a balance dominated metagame into a more offensive metagame where stall has also become increasingly popular, and that's a good thing. Now these playstyles are more common, leading to a greater variety of teams. My thoughts on the "we should totally ban Greninja because it makes balance an unviable playstyle!!!" (looking at you
MegaScizor and you
-Clone-) is that this is such a silly, wrong, concept. First off, we don't ban things just because they destroy a playstyle. Kyurem-b broke stall in BW2 but we didn't ban that. Similarly, Gothitelle destroys many common stall builds today and invalidates a basic game mechanic called switching, but we're not doing anything about that either. Just because Greninja completely destroys balanced builds (which isn't even true at all. Sure, HO and full stall have a much easier time against Greninja compared to balanced teams, but still, balanced teams aren't helpless; they have some checks like the common Ferro, gyarados, rotom-w, keldeo, etc) doesn't mean it should be banned. In order to ban something, the pokemon should either be "broken" or "uncompetitive", and Greninja is neither, which is why I think it deserves to stay.
Theres also the argument that "Greninja overcentralizes the metagame as much as Aegislash and promotes lazy teambuilding, and if you don't pack at least 3 checks, you're dead" which is also untrue. Greninja isn't even
remotely as overcentralizing as Aegi was. Aegi made like 10+ pokemon unviable, or rather lackluster choices in the OU metagame which otherwise would be top tier threats (medi, garde, hawlucha, alakazam, celebi, starmie, heracross). These pokemon were all uncommon at high levels of play JUST because of Aegi. Greninja doesn't do that. Sure, ninja now beats clef and azu and all that but the point is these mons are still very common. Greninja doesn't overcentralize the metagame like Aegi because it can't even fit on any type of team. If you're running a Greninja on any playstyle that isn't offense, you're probably doing it wrong. On the otherhand, Aegislash fitted on every single team out there ranging from HO to heavy stall. Now for the "you should always pack 2-3 checks for greninja otherwise you're dead" argument
Destiny Device , this isn't even true most of the time. Sure, balanced teams might think about this commonly but I can bet you that Greninja isn't a major concern at all for stall builds who don't even consider Greninja a threat. Offensive teams aren't even that pressured by Greninja and don't consider it a major threat either due to the prevalence of scarfers, hard hitting priority, and faster, stronger attackers. They're much bothered by other things like mega lopunny and sand excadrill. Another point is that just because you require checks in order to not get destroyed doesn't mean you're automatically broken. If you don't have like 2 thundurus checks it steamrolls you. if you dont have a keldeo switch in it gets a kill each time it comes in. It's all the same concept.
Now lets go over how Greninja fares against all common playstyles. First, against offense. heavy offense actually fares quite well against Greninja. Sure, offense teams probably don't have any direct switch ins against Greninja, but who the fuck cares? It's heavy offense, it's not supposed to have switch ins to anything. There are tons of things in which offensive teams don't have a switch in for. A good example is CB azumarill in the XY metagame, or even mega garde which basically got a kill everytime it got in safely. offensive teams dont need a switch in to Greninja to beat it; they have tons of offensive checks to it, and they are able to pressure it immediately and limit the number of times it can come in safely. Greninja will be hard pressed to beat offensive teams because of the absurd number of checks on the other team: mega sceptile, mega lopunny, talonflame, exca in sand, breloom, bisharp, scarf lando-t/chomp, thundy can paralyze, mega aero, mega beedrill, dnite espeed, not to mention all the rain HO teams that just shit on it. You might use the argument that "well greninja can always switch", but think about it, can it
always really switch against HO teams? switch against a talonflame and it'll SD and sweep your team. same thing against bisharp, and it even has pursuit to trap you. switching vs scarf lando-t just makes things harder for you cuz then it can just u-turn and regain momentum. HO fares very well against Greninja.
Now against stall, Greninja really struggles to put in work. Stall, quite simply, does not give a fuck about Greninja at all. The most standard stall build (sableye/chansey/tenta) walls ninja to hell and back, even sableye can check it with priority CM + recover. you can sugarcoat it all you want by saying greninja 2hkoes chansey after 3 layers of spikes and you can extrasensory tentacruel, but the fact is
greninja isn't getting past stall. how are you gonna get 3 layers of spikes down when tentacruel spins on your face? how are you keep going to fire move after move when LO and hazards damage are taking your toll? and even if you do have extrasensory to beat tentacruel, it only 2hkoes at best, and you have to drop dark pulse. and against stall, there are always bulky psychics to take advantage of that fact, such as jirachi, slowbro, cress, etc.
Balanced teams undoubtedly have the worst matchup against Greninja, which kinda sucks and they'll be forced to adapt, but hey what can you do about it. Similar to how stall had to adapt to the increasingly common wallbreaker megas after the Aegi ban, balanced can also adapt to greninja and not be a shitty style based on fat mons + 2 powerful attackers. balanced teams arent helpless against ninja, they just have the most difficult matchup. ferro and specially defensive rotom-w are good checks, and if you get scarf lando-t in safely you pretty much get a free u-turn against their team. one less common and unique pokemon that actually works really well on balance atm is klefki, which also has the perk of walling and crippling greninja with thunderwave. specially defensive mega scizor is also a really god switch in, and you can even run some other cool stuff like scarf/chople berry kyurem-b.
Becuase of all these factors and my reasoning, I will vote
DO NOT BAN on the suspect test.
