Gen 3 - BAN REQUIRED

This seems like an overreaction to me.

You claim that evasion abilities were banned in other generations due to being "uncompetitive". The way things actually turned out was: initially, Garchomp was banned because it was too strong in DPP (Sand Veil Substitute sets were very popular and a contributing factor). Then later when a few other things were banned, Gliscor began to show up as another very strong threat with Swords Dance and Sand Veil. At this point, from my perspective, there is a significant chunk of Smogon's userbase that wants to ban any RNG elements they reasonably can, so instead of banning the actual threat, the userbase (when given the option) voted to ban evasion abilities under Evasion clause, resulting in a bunch of weak Pokemon also being banned.

Calling all/arbitrary RNG elements "uncompetitive" is frankly nonsense. There are a massive number of competitive games with huge RNG/chance elements. Virtually all card games have a massive RNG/chance element and everyone knows they are played competitively. Pokemon, similarly, has a lot of chance and RNG management. Banning things that are not too strong is unnecessary and from my perspective, the result of an emotional overreaction. Note that I am not saying certain methods of invoking RNG are not too strong, because this is clearly the case sometimes. Cacturne in RSE OU is not one of them.

There are also many extremely similar game elements that people take advantage of and barely anybody seems to want to ban them (e.g. paralysis + substitute, flinch moves with or without substitute, confuse ray, etc). [post di Earthworm]

More new players would likely be put off by the fact that we allow a permanent evasion ability than just seeing in teambuilder "Sand Veil is banned".

I'm not a fan of abilities / conditions that can influence the outcome of a game strongly based on little to no fault of one player. Additionally I'm no purist in the sense that I think we need to preserve as much of the original core gameplay as possible. Sand + SV is incredibly unfun to play, incredibly niche and has precedent to be banned under our structure for other tiers. I don't think we as a community gain anything from keeping a strategy based around coinflips, I felt the same for swagger in BW and feel that way here. [post di teal6]
