You have in your sig toons on both sides of the civil war. Did you not know you can mail credits/items to your alts in the other factions? That's how I was supporting my rebels.
Does it matter? All playing both sides does is make me realize how much easier Imps get everything. Not everyone has the benefit of having toons on both sides. In any case, my Pub and Imp 50s are on different servers.
One example - My Operative started HM Operations two weeks after turning level 50 and was in full Rakata a month after turning 50. My Scoundrel just got her first piece of Rakata two months after turning 50.
Either way, it still doesn't make much sense that the most efficient way of farming money is doing an Imp-only mid-level flashpoint.
