Having used FTL I would recommend you not use it if you have no interest in arenas and arenas only. BG PvE no one cares to see who is the leader or who is being focused, only arenas does someone really pay attention to that. I currently do not arena and wish that I had gone the focus route. FTL has a few annoying things, one being that it eats up most of your macro space with targetting. I can fix it sure, but I have it working and am not motivated to do anything about it.
