Unless you want a decent Hail sweeper immune to Rocks. And again, Pre-alteration Syclant had pumped offenses and the absurd 121 Speed. He was a nightmare in the beginning which is why he was toned down.
In the beginning Platinum wasn't out. Scizor had not Bullet Punch. The metagame was completely different. So it is pointless to compare.
So we're making a Snowdra that doesn't actually need snow?
Another huge strawman. I'm starting to get sick of them. Try to apply what you are saying about Snowdra to Kingdra. Does Kingdra not actually need rain? Obviously it enjoys it a lot, but it can very well function without rain. Same thing would go with Snowdra. Hail would not be a must, but a huge benefit to his sweeping ability.
No team needs any one pokemon, though Hail obviously benefits from Abomasnow. People have already run successful Hail teams without the need for this CAP. We'd be filling a niche that needs no use, or we'll be inventing our 3rd Fighting or 2nd Steel type CAP on the basis Tyranitar craps all over hail.
People have already run offensive teams without a Pivot Point. People have already run paralysis-based team without a Para-busing tank. People have already abused with good success underused Pokémon with interesting abilities. People have already utilised multi-attack Pokémon to break things like Subs. With this logic, every CAP could be deemed useless.
Otherwise we're just creating a CAP that doesn't particularly mind facing Hail teams, likely leading to a decrease in their use.
So you would say that the very existance of Kingdra hinders in the same way Rain teams? This is ridiculous.
Again, if you just hate this idea, say it. But do not try to find non-existant fallacies, because this is insulting to people who actually support the idea. If I have a specific issue against an idea (like EM's lack of direction) that's a point, but do not start bitching for the sake of bitching (Even if I do not like your idea for example, DK, I have never criticized it for the sake of criticism. I'd like the same respect from your side)
