Hmmm... That's an idea I never considered, though I'd hate to have nothing to do simply because I ran out of PP and can't use the regular attack. On the other hand, if the duration is long enough then the ability to keep a weak shot up closer to constantly and switch locations if there's some part of the boss you need to damage other than the weak point has its merits, especially considering the AR has crap damage on its regular attacks and multiparty areas mean you can give that damage boost to as many as 11 other people as well.

I guess there's merit to the idea, though switching to launcher would probably remove the remaining shots so people who main launcher should stick to 1 point at the most.
