Ignore what the others have said dude, I lvl'd an imp agent to lvl 50 myself and had an absolute blast with it. Was a mix of warzones and pve missions.
Now that he's 50 he still has no advanced class and I still take him out for a spin in warzones. still a lot of fun.
Nice to see a other agent ^^
I keep my eye's on the server for agents but every agent i see stops around being there treu role around level 12
