The initial posting of this thread is misleading. Cause and effect are mixed up.
It is not Anti-Proton whose damage has gone through the roof just because of the proc fix - it is the general DPS of escorts using cannons and also having specced in the new skills that makes stuff die even faster than before.
Stuff just dies too fast, be it PvE or PvP.
I experimenated and if you use Engines settings (25/100 Weapons only), battles are actually fun and engaging...^^
To put it bluntly, purple Anti-Proton guns did not suddenly get elevated above all other weapons. We just do by far too much damage, which is both harming PvE and PvP alike.
i just explained why the +20 crit severity is more potent than other procs. it procs more.
