In regards to Double Team, it's almost common practice now that if the original pokemon is hit, then all the clones vanish. Does this not seem a little unfair, given that DT is a stat booster for Evasion. If you manage to use Double Team six times, one lucky hit puts waste to your +6 evasion. Whereas there is no such instant dampener for any other stat. You can't instantly cure -6 accuracy by hitting a target, or knock down a +6 attack by defending really well.

My point is, should clones vanish at all? They're meant to be illusions, as oppose to a physical presence. Them being hit by an attack, or even exposed to falling rain shouldn't matter if they are just shapes made of light.
