Star Trek Online will be centered around the Federation faction, which is somewhat unfortunate for fans of the Klingons who have their hands tied to PvP career advancement, while the Federation have both PvP and PvE to choose from for ranking solutions. The Federation faction is indeed well-rounded and has advantage over the Klingon regarding the more player vs. environment content available. But ultimately, both factions will have the same number of skills and the same professions.
The differences in the two factions lies in the alignment of the weaponry of the ships. The Federation ships are well-rounded with beams equip-able in the front and sides, unlike the Klingon that are more oriented to weapons placed in the front of the starship. So you will know exactly what to do when encountering a Klingon ship. Just focus and shoot the side of the ships! However, beware because these Klingon come equip with more bridge officers that Federation could ever think of. Players could be sure they got some boosted attributed hidden under their sleeves, but again it depends on the players and how much of an advantage they can allocate bridge officers to give them that edge in battle.
I am coordinating with some fellow writers to get quality Star Trek Online Federation Guides out in time of the game’s launch, as well as many more comprehensive Star Trek Online Guides.
