Need Help on a Training spot for Marauders.

Yeah, thats the problem, I went shockwave by mistake. Right now i have 18 energy charge, 19 shockwave, 1 transform, 20 stun mastery. As you can see, I used the skill-build that was on the sticky topic. I regret it now, but there is no turning back when you have gone this far. Is there any place where I can train? I tried ghost ships, but they are the same as kents.
Am I doomed? : (.
