Relatively is a nice word. This will never be the case, and people realize that and exploit it all the way. Rakata medpacs, stimpacks, adrenals, rings the bell? In 1.2 my character cannot wear augmented boots and gauntlets, because I'm only PvE-ing and crafting. Not-PvP-ing limits my PvE capabilities. So if you're only PvP-ing and crafting, this should limit your capabilities as a crafter. Everything is intertwined, always.
Well, they should be economically intertwined, yes. But that's pretty much it. Bioware is (slowly) removing the rakata advantages. The boots/gauntlet issue is already being rectified as well. Just because they've made mistakes doesn't mean those mistakes shouldn't be fixed.
