Imp vrs Rebel battlefieldFollow

I just recently got Master Commando and Master Medic(im out of points btw), so im done running missions and going on creature hunts for exp. So I have 2 questions, What do I do now?(im not going to try to become a jedi).And also where is the best/most populated Rebel Vrs Imperial PVP battlefield? Please only answer if you have been to that particular battlefield or are 100% sure the battlefield is the best, no i think this is the best, or my cousins brother's sister has been to this...etc

Im on the Scylla server btw (that might help, da)

THANKS!
