Regarding sticky web; even if you remove it, you'll still be slowed by it before you did so; just something I thought I'd point out, doesn't change too much though.
I'm on the yes side for this too; the new threats in gen 6 combined with the nerfs to rain weather are enough of a reason to move it down to OU (though there it still has the capabilities of hydration and tail glow (but not rest, in my opinion, since it can waste the amount turns you have with drizzle left pretty quickly)).
