yes from what the OP said about firing in his face with AC i assumed he was talking about those DPS style ac2
i could be wrong though -
edit: well maybe my main point didn't come across, the shots you take with ERPPC are disposable - not only fire and forget, what do i mean by this? the damage is good on ONE erppc shot. so if you get shots of opportunity, they count! unlike most AC that is not ac20.
they fly pretty fast too
but the main reason that ppc shots are disposable is that they only cost heat, there's no ammo to be careful with. you need to exploit this fact and make it work in your behalf.
if you pair up these characteristics, long ranges, high flight speeds, high damage, no permanent cost on your arsenal>
you have a very good harrasing weapon for the long ranges the ERPPC can shoot at - your wiggle room is there, the autocannons have high flight speeds also and long ranges but the damage on most is a bit lower and they cost bullets so you gotta try and make it a marathon, not a sprint when going up against them - make them work for their shots while you can be careless and make shots that will miss because who cares? just shoot through every cranny between buildings in river city, why not?
also for ac2 and ac5 if you can get a good spread on your torso by twisting, the damage is very minimized. not so much with ppc shots, in particular if they're both fired from the same barrel at the same time or just with good convergence, several ppc shot is devastating and no ammount of twisting will help you, which is why the big nerf was made
EDIT2:
another thing i wanted to add to the OP is that if you want to "boat ppc" on this game, much like boating LRM, you're going to need support weapons. never go out without your green lasers for close range fights.
separate the weaps you're going to use for lrming (or sniping in this case) from the more "user friendly" guns that are more suited for close range fights.
on one of my mechs i use mainly green lasers, on another mainly srm - of my 2 awesome ppc boats.
