imo the biggest problem you've got as a PE nowadays is the uselessness of lower TL lowtech weapons - ever tried a terminator ? the pain easer ? libby anyone ? even if you hit, you don't do enough damage to seriously get an opponents health down, since the TL40 healtool is pretty powerful. this makes resist-setups almost useless, at least that's how i experienced it as long as i played an PE (since 2.2, first on mars, now titan);
if you look at lower TL hightech-weapons, we got the RoG (for riflers) which is basically rubbish in PvP because most of the time the hits won't register (if they would, it would be a pretty sweet gun); that leaves you with 2 choices: sacrifice PSIuse to dex, and be a shittier version of a spy, or go woc. same with pistols, since the judge does almost zero damage as far as i remember, but i'd love to be corrected by anyone who knows more about this than me, i've not tested it yet...
solution: boost guns like the terminator with stacking damage as before; give them poison-mods (not sure about that one, but it might work), and boost the damage of guns like the judge. and if the RoG would work, that would be the absolute top icing of the cake.
p.s. yes, i know about and love the desperado, but as far as i remember even that one could do with a TINY boost in damage...
