Im trying to buy the exalted gear from the vendor on. Dromund kass

I doubt i,m the only player to think "i really want to play that mission again, shame its done now" when you get to the end of your story campaign, even though i know people just make a new character of that class to do it again but some people may not fancy havng to go all th way back through and only want to replay one or so specific missions?

Ive been using my main level 50 marruader to crack up the credits by doing some of the dailies in section x and black hole, but ive found that even though it is very good credits for 2-3hrs tops it isnt as much as i was hoping to earn in that time. Plus the fact im trying to gear my newly made level 18 merc its hard to keep his gear up to date when my credit income isnt really that great, any simple advice on the best way to achive this would be super helpful

Just read the replies, thanks for the help :D

I've been leveling a pyro a little while now which is fun but I find it takes a while to run through multiple mobs at once, could anyone give me any friendly advice or possibly link me to their own tree stats so i could improve my own?
