hello guys... unlike ArVaDa ^ (btw I totally respect you as a player, and respect your opinion, but I have to disagree with you on this one) I want to believe that the council does take the input of the community on making desitions, soo yeah....
Now my thoughts on the supect/bans (I also believe that voting from all players that want to cast a vote in this forum should somehow influence the desition)
first I start with the zapdos Ban, lemme start by saying that first, I think that it's not a bad choice, but if the council really wanted to hurt flying from a defensive core standpoint they should've banned skarm (that thing is more toxic than zap, has sturdy and is THE BEST phisical wall in the entire game, sorry Maggron). But overall a good ban, even tho with flying being flying it has a plethora of other mons that can fill the role (although not quite as good as zap did it, but still good enough)
2.-Smooth rock suspect: See, the problem here is not excadrill being an amazing sweeper as it needs support and really sturdy phis walls screw it's field trip over teams, and as a lot of ppl said be4 me, IT HAS CHECKS (even thou shaky ones but it has, unlike Megagross). Also we should take into account the hippo (I've heard ppl say OML BAN THE HIPPO!!1!one)!, to which I have to say "lawl", yes I know is also one of the best phis walls, and also a good mixed wall that can tank SE moves from a lot of things it shouldn't take, but if you want to ban a thing for being bulky and setting sand aka doing its job (totally not broken) that's like saying: "let's ban mew/slowbro/swampert/torkoal/ferro/chansey/forretress/avalug/politoad/every other good defensive threat" is just nuts. The last point about the ground nerf I've heard of is the baning/suspect of Lando-I, and I think that here is where you're getting it right, yes I know it sounds just as stupid as the banning of hippo (which is the supidest thing the council can do) but hear me out, Lando-I destroys a lot phis walls that can threaten the drill, it has enough bulk to take a lot of neutral things (is not like ppl start running ice beam on everything, [and that was sarcasm btw] ) and it has only one true counter which is my beloved moonduck aka Cresselia (but I've seen some Landos carrying toxic but that's just eww and lawl) so yeah, Lando has amazing synergy with exca, also they can take out each others checks, unless you have the best mixed wall ever which iirc doesn't exist and they are both inmune to paralizys (not counting stun spore cuz accuracy and also lando carries sludge bomb for those pesky grass types and psy for those poison-grass, and the stupidly coveted glare) also has an amazing speed tier, and it can run knock-off and u-turn to hurt cress (considering that cress loves its lefties and under the sand doesn't gain all the HP with moonlight) finally it's just too strong for many walls to handle, so I say suspect/ban Lando-I, not ban excadrill, and lawl hippo. Smooth rock is not as OP as damp rock.
3.-Charizard-X suspect/ban: CHar-X is amazing by itself, and provided the right conditions (I've noticed that early game Char-X is much more usefull than mid-game, also it's an amazing late game cleaner) is completly unstopable, (yeah who lets it set up, right?) I've seen a lot of comments saying that you can't give it the chance, the point is all you're mentioning are hyper-offensive builds (like bug and fighting) but lets not forget that balanced and stall are also huge play styles in the meta (and sometimes those players simply can't stop it from setting up) I myself (laugh all you want) run a scarfed jirachi with draco meteor that takes like 50% of its HP (that was when I didn't used slowbro, I had to use cresselia to stop landorus, and more than one phis wall can't happen on a team, now things have changed and use slowbro as a mixed wall with ice beam lol, weird sets and adapting galore).
3.B.-here's where the point I previously made about zapdos comes back, yes, flying has a plethora of other mons to fill the roles of it (unless you're skarmory, which let's not kid ouserlves, nothing quite fills the role by even half of it),A lot of ppl say that Char-X is just gonna get replaced with another Mega dancer that resist bolt-beam, which is not quite true, the only two choices flying users have (the ones that have been discussed previously here) are Malaria (Mega Altaria) and Mega gyarados, which, lemme say MAltaria is weak to ice attacks (like I said b4, ice beam on everything) and also has two other weakness (poison and steel so Mega venu still shines against the flying mega), and gyarados (who doesn't like to mega 1st turn, as it likes to dance while non-mega) is weak to tbolt (4x non-mega, regular weakness after it, also has a 4x weakness to freeze-dry), and it has a weakness to fighting, fairy, electric, grass (again mega-venu killing them mega-flyings) so yeah, like I said: "flying has a plethora of mons to replace something (unless you're skarmory) but the fill-ins don't quite do the job the same way. Also both megas aren't as fast as CHar-X and their abilities are not as powerfull (as in mold breaker works mainly on sturdy, levitating and what not, which is nice but a niche and Pixilate only boost normal turned fairy moves, amazing but wall-able.)
So IMHO say that: Ban/at least suspect Mega Charizard X if you think its prescense its toxic for the meta. If not you can re-introduce him if you think its lack of prescense is unhealthy..
Tl;DR: Not Ban on excadrill nor hippo nor smooth rock, Ban on Lando-I and suspect/ban on Mega Charizard-X
sorry for long post and for grammar errors, english is not my first language, also I know I'm not the best player and that I can be biased, but I tried to be as objective as I could.
