Also just want to say that banning non-broken threat after non-broken threat because "no switchins" is how RU ended up with a metagame in which fucking Alomomola was considered broken. (can't even apply the no switchins argument to Entei though so wtf)
lol. alomomola was never considered broken in any metagame that we have had, and i am very curious to hear what non-broken threats we have banned. was it sharpedo, the mon that completely invalidated offense as a playstyle? was it durant, the mon that ripped through whatever playstyle it wanted depending on what item it was given?
anyways, this is not directed solely at you dodmen, but this argument that there are a plethora of viable entei answers is just not correct. calling mons like jellicent, slowbro, slowking, and diancie 100% switchins is just wrong. people have this idea that entei can not viably run z grass, so i wont even use that for my argument, but diancie is 2hkod by stomping ttrum, and has no reliable recovery. on top of that, diancie can't even ohko entei, and it's forced to run a lot of spa investment to force things like mandi out (so you can't invest a lot in def or like atk for diamond storm). i am not trying to dismiss diancie as a good entei check, because it is, but diancie team comps all are very similar due to the mons that every team has to cover, and they often have lots of trouble with offensive grasses. jellicent is also a good answer, but it is definitely not an easy mon to fit on your team because of all the mons that milo checks better than it. you're almost forced to pair your jelli with shaymin and/or toxicroak, and your team is still going to struggle with mega stoise, which happens to be one of the best mons in the tier. similar logic is very easily applied to slowbro and slowking, and lax is very easily pressured by entei and forced to be asleep for the whole game. the figy facade set would be a solid entei check, but that set has an incredibly hard time doing well in ru due to the prevalence of toxic.
this idea that you guys have about ru players refusing to adapt makes no sense because if you use these more niche bulky waters your team will have even bigger problems than entei. for the sake of argument lets say you could make some perfectly constructed team with one of these other waters. what does that do for the argument that entei is healthy for the tier? those waters are competing with milo for the same slot guys, they don't open up some crazy, unexplored team compositions. this leads me into my next point; entei heavily restricts building.
i do not think entei restricts building because it is inherently broken, but i do think entei was in a sense the straw that broke the camel's back. entei is a top tier mon that invalidates its offensive checks because of its main stab's burn chance, provides solid defensive utility due to it's fantastic bulk and typing, and has great cleaning potential because of banded espeed coming off of base 115 attack. entei puts us builders into a box because it heavily promotes these cookie cutter balances of zong/regi, milo, gligar. milo is by far the best reliable answer to the cb set, and it also counters one of the other best mons in the tier in stoise. i have very little reason as a builder to, for example, go with a rhyperior stoise team because it's simply not good vs entei. my rhyp gets burned and can no longer keep up rocks (not to mention it's setup bait), and my stoise can get 2hkod by flare blitz if it's not mega'd yet, and if the entei sacred fires, scald is a 50/50 roll.
i could go on for days as to why this mon is unhealthy for the meta, but i wont. at the end of the day y'all will vote how you want, but i just do not want this false narrative about entei's checks to be universally accepted. i don't even feel like having to explain why mons like dragalge, noivern, and gligar are not entei counters in any universe, and are even bad checks, but just very quickly so that my argument is somewhat more complete, i will.
dragalge can not effectively run a defensive spread in the metagame, and even if it could it is 3hko'd by every move entei clicks, and fails to even ohko back after rocks. noivern is not even a check because z hurricane doesn't kill, and it can't even come in on se or espeed to get off damage. gligar is a horrid counter because a burned gligar loses to registeel (among many other things), and becomes complete setup bait that's essentially forced to roost more than it should, and click u turn.
in conclusion, if the current meta had a few less offensive threats entei could be a fine addition to the tier, but due to the state of the meta combined with entei's lack of reliable answers, entei should be banned.
