How about the fact that you can't even do PvP (FvK) until you're a Commander (as Starfleet). This ****es me off.
I'm not exactly new to the game but I haven't played it for 2 years and the game has changed quite a lot. This being one of the things I just recently noticed. I went to the Neutral Zone with my level 9 Lieutenant character to fight against other same level Klingon players but apparently this isn't possible anymore because you can't be a Klingon until you're level 20-something. I have no interest in Fed "wargames", I just want to get down in the dirty frontline battles against our enemy, the Klingons. But smart and adaptable Klingons, not the unimaginative ones I face in PvE.
So this is very unfortunate and makes me less inclined to care about PvP.
