I am in no way affiliated to any gallic factions but i think you all should join or make a new faction in Galia. First because you are so many and in role play gallic are numerous and second because there is a need for new players like you that dont have a bias towards other factions.
So basicly you can take over an entire house and decide its politics and strategy. With so many players you can mount organized raids that will obliterate any oposition. Of course you will suffer great losses because you will find more experienced players against you, but with so much force you will win and that is exactly how Galia should be.
You will get lost in Liberty and lose interest because you can not integrate so many players. Plus there are too many players that just troll in Liberty.
This is my personal opinion and this is what i would do if i had so many friends that could get organised.
I wish you best of luck and i hope we will meet ingame.
