ahm... i don't know about you, but i personally think this is one of he worst ideas i've heared lately..
if you make bursting 14 APs, if thats even sane, you'll be taking away any low PE crafter builds chance of defending himself, from the power builders, who will use miniguns still, and waste people who cant take that one burst of damage they get off.
also, if you look at this from a real in character stand point, what is a minigun? well, unlike its name suggests, its a really really really big burst gun, which, is normally mounted on vehicles or planes if anything like it in our real world armies like it is used. thus, it should be powerful. and Balence? you're putting up a minigun vs a knife/pistol/SMG/assault rifle, in pretty much any game that'd be a easy win for the minigunner.
as for some notion of "giiving crafters a fighting chance" meh, the reason crafters often loss is they don't shoot first, and if they wear any type of armor they risk lossing it, or rarely they get wasted by anti PKer groups guarding cities. ask Lacan/lacanette if you see him/her about that time with Ulrek in the broken hills for a example..
and finally, the most i would ever cap the skills at is 200, and even than, with the powerbuild vs crafter thing, they'll still be one wearing metal armor MK2 and one guy wearing a bluesuit or leather jacket in those little battles.
cheers all.
