I never claimed that Milotic was broken, and while I generally agree that that is a horrible argument, there are some cases where a pokemon that counters a broken pokemon isn't broken itself. For example, Umbreon counters Latias. Are we going to call Umbreon a suspect simply because it beats Latias? That is silly. Now, recognize this isn't a perfect example, but you get the point; A pokemon capable of countering a broken pokemon isn't necessarily broken. Is Chansey broken because it keeps Moltres from definite suspect status?
I apologize for the slippery slope argument before, but it is true.
That was not the point at all.
You are taking what I said and either misunderstanding it or twisting it into something that is undeniably incorrect. What I said was: "Not banning a broken/not broken Pokemon for the reason that they check other would-be broken Pokemon is fallacious.", I did
not say that "if a Pokemon checks another broken Pokemon, then that Pokemon is broken" because that's obviously false.
You're really only proving my point about including a reasoning requirement....
I don't think anything will come close to Cresselia as a defensive behemoth. While Milotic does come close, there are two things that keep it UU status in a nutshell: 1) Prone to entry hazards 2) Coverage problems. Unfortunately, a majority of the metagame does not apply to Milotic with the latter problem. If it doesn't have Hidden Power Grass per se, then it cannot hit Water-types and if it doesn't have Ice Beam it will fall to Grass-types easily. The common set runs Haze in the slot, but if Milotic is seen lacking one then it will fall prey to boosting Pokemon. The first problem is probably a big reason why it is not going to be BL since Spikes is common in the metagame and it places Milotic is 2HKO range for certain Pokemon like Arcanine, Rhyperior, Moltres, etc. Unlike Cresselia, double-switching will not hurt it since it is immune to Spikes, but on the other hand, Milotic is part Water-typing and double-switching can easily exploit it and rack up its damage quickly. If we look at the defensive characteristics, Milotic will not wall a portion of the metagame with the reasons I stated. It either has to run a set of Recovery / Haze / Surf / Ice Beam / Hidden Power Grass to wall a majority of the metagame. Edit: I'd like to add that Milotic falls prey to common offensive combinations and unlike Cresselia, it was simply impregnable even if you're using offensive combinations to attempt to break it.
I find it ironic that almost everything you say about Milotic applies more to Cresselia.
Coverage problems? Milotic's two-move coverage is actually much better than Cresselia's, but Cresselia can't actually stop most Pokemon from setting up unlike Milotic. If Cresselia runs Psychic, it either fails to hit opposing psychics by using Hidden Power Fighting, Steel-types and Dark-types with Shadow Ball, Steel-types with Signal Beam etc. Not to mention that Cresselia has a pathetic SpA stat compared to Milotic's base 100 SpA stat with a 95 BP coverage move as opposed to 70 BP like Cresselia.
Falls prey to boosting Pokemon without Haze? Hi, my name is Cresselia, and I am the easiest Pokemon to set up on besides Chansey.
Spikes are not as prominent without Froslass, and even so it is not 2HKOed by Arcanine, Moltres, or Rhyperior (it outspeeds you).
To me the main difference between Milotic and Cresselia is that you essentially need to use two Pokemon to reliably get passed Milotic, while one Pokemon can set up and end the match vs Cresselia.
Status also fucks up Milotic, while Cresselia had several viable ways to remove status. The entry hazard thing is also big. Cress only took Stealth Rock.
Please enlighten me as to why Cresselia is less vulnerable to status even though status actually makes Milotic harder to kill. Rest + Sleep Talk? Oh wait Milotic can do that better than Cresselia...Uh Substitute...sure, but now your Cresselia is using the infamous "252 EVs in every stat with 16 moves" set. Milotic can use Substitute in that scenario as well.
