I don't really why you're thinking the powerup fx will be change in B1.2 ... but ok
instead of saying "make it better" just say how it would be better ... give a solution to make it looks better (it should be possible in HL engine, shouldn't drop your fps so much and it shouldn't not look like the turbo aura (like in alphas)) ... then the team can decide about it
I think it's ok the way it is now
