I hope all of you people who are discrediting others' input purely because they're on a PvE server realize how retarded you sound. You're declaring it literally impossible for anyone who plays on a PvE server to know anything about PvP? I play pure PvP on a PvE server, and I'd bet all of my real life assets that I could absolutely roll you guys in any aspect of PvP with any class. The server doesn't decide the skill or competency levels, folks.
And I'll add this simple inquiry in support of this thread - If 60% armor pen was too much for scrapper/concealment operatives (Which I, as a scrapper scoundrel, agree was too much), why is 90% not too much for pyrotech/assault specialist powertechs? Before you naysayers try to shoot down this post by telling me only Rail Shot gets 90%, let's pay the slightest bit of attention and realize that every other attack they do is elemental damage, which everyone only has 10% reduction against WITH the consular/inquisitor buff.
