Not sure what I will do now, unless I can get another 700 CC. I have a 50 Marauder and a 49 Pyrotech on the Bastion. Those were my mains until we hit Bergeren. I have a 42 Juggernaught I want to bring along too. The problem is, I like the Jug better than the Marauder but the Marauder is 50. Decisions, decisions.
Personally, I say bring the one you enjoy the most. Are you a sub or f2p? If you're a sub it will only take two months to get over 700 cc, with some left over. I would love to bring over three (smuggler, trooper, and sorc), but I can't afford it all at once. So I've re-rolled a few, but with diff adv class (good to learn a diff playstyle imo).
On another note, I read a dev post on swtor.com that said there will not be any restrictions on server type. Meaning you can transfer from a PvP to a PvE server, ect. Yay!!!
I'll probably won't transfer immediately. I'll give it a day or two to make sure there aren't any major glitches, and for a few more sales to go thru on the GTN, lol. But if all goes as planned I should have my lol 55 smuggler on board by the end of the week!
