I am new to the game, and knew Klingon. I played as Horde back when WoW first came out, so I am used to being the red-headed ******* step-child no one loves. I am all for more content, but for now I find quests I have adequate because I spend a lot of time in PvP queue.
I am all for more content for this faction however, and I am all for new factions int he future (Romulans and Cardasians).
One thing I'm not for thou is wars which make little sense :/ As much as I enjoy slaughtering the Feds, I would rather that wars in the future be result of player actions especially once we have more factions and possibilities for conflicts become more that one.
