I can only agree with the above posters Rough Skin Chomp is perfectly fine to handle, but with Sand Veil it's getting ridiculous. I see absolutly no reason to keep Sand Veil in the meta game it's only creating another luck factor nobody wants (except for some NU players that don't want Cacturne getting nerfed). Sand Veil Gliscor was already annoying and something i hated to face everytime i didn't ran a Rain team, but if you give something like Garchomp a 20% chance for invincibility against virtually anything as long as Sand is up there is a good chance that everytime that chance activates the opposing player faces a completly undeserved disadvantage that can likely cost you the game. Comparing it with Moody might be a little too much however i don't see a reason why it shouldn't be banned under evasion clause together with Snow Cloak (wich would just be consistent and i don't see many relevant pokemon that would suffer from it now that Mamoswine got Thick Fat).
I am usually someone who wants to keep the ruleset simple, but right now i would say either Garchomp leaves or Sand Veil gets banned, because right now i have no more desire to play on the suspect ladder as i would propably smoke one pack every 3 hours in order to keep calm ^^
