As far as I am aware of at this moment, you can crossfaction team during a private pvp match. It happened to some fleet mates and myself. We have not tested the theory on STFs just yet, but are hopeful that it might be so.
I actually happened last nite during pvp. We had decided to run 2 klingon toons versus 2 fed toons for the heck of it, then we mixed and matched them a little. The game allowed the mixed team to actually team up. It was nice for a change
And thanx for the info about STFs I wasnt sure about that yet
I kinda doubt that a merger will ever happen, all of those type of ideas and rumors have been proposed by players alone, not Developers. If it were to even be seriously discussed by the Dev team, I would strongly oppose such.
But, cross-teaming, especially on the STFs I would be in favor of.
We worked together during Operation Unity and drove the Adromedans all the way back to their Homeworld, we can do the same with the Borg.
