Well Cupcake and I are not F2P we are subscribers as is my son. So I don't know all the limitations of the F2P but I do know F2P accounts are restricted from Warzones, you basically have to buy a pass.
Currently we are all on Jedi Covenant Server which is PVE, I have a Jedi Knight(Galvaron) on Jung Ma which is RP-PVP, but I haven't used him in a while, he is a lvl 32. I should level him up, but RP-PVP is tough a lot of areas are open PVP so you can literally get jumped by Imperial players. It's smart to travel in groups.
The Guild is on Jedi Covenant, with about 9 members who are main and alts, right now its my son, Cupcake, Me and Cupcakes friend Penda-carcol. But I haven't seen Penda in quite a while.
