I have a 50 hunter, was pretty fun leveling up, didnt have any problems or anything. focused around the bloodwing more than gun damage except for the last 10-15 levels when i had points to spare.

i tried making a soldier. hell of a lot harder so far. not sure what to put skills into because idk how much the turret really helps

tried making a siren over a friends, dont see what her skill really does. i know it makes her run faster and invisible, but is there a twist to it im missing? its not really good in comparison to other beginning skills. does it just take a while to get good?

The burst when she goes in/out of Phasewalk does very high damage later on. And if you up the skills to increase your melee damage it gets INSANE! My Siren does 2k melee damage

soldier turret gets powerful w/ arifacts

the sirens phasewalk does a good amount of damage when entering/exiting the ability, as well as extra melee damage when in phasewalk, and if you upgrade the hit and run to full she becomes pretty beastly with melee damage durring phasewalk

so go for all melee damage then and slight advances to guns (like the modded weapon i have :] )
