I see your reasoning.
I raise you specific counters. For the evasion factor in rain/hail/snow, if the shapes of light are made out to be not solid (ie you can see sand go through them, but not of the actual one) that already reduces your evasion prowess to zero.
As for the one hit and they go poof. The amount of times it takes for that one hit to occur may take all six tries. Yeah, it sucks if it is the first go around, but Double Team also does not raise your evasion by one like the games in ASB. A random number of clones appear and its from those clones that your "evasion stat" is increased.
You may only yield 2 clones, or you may yield 8 (after multiple times, yeah)
But, I'm interested in hearing more about this. It does seem silly to nullify the Double Team clones entirely, but Haze does that with no problem, why can't other weather conditions? It just doesn't seem right that after hitting the real one, you would hit the fake one again.
Anyone else wish to chime in though. We're open to interpretation of this. DT could be in use of a remodel for ASB mechanics.
(and Haze/Clear Smog laffs at your instant dampener comment)
