Assault class tips?

Been playing the game for a while and enjoying it, despite not being all that good. Managed to get every other class to 25 except Assault. Only about level 8.

I just can't get into the class at all. Don't like how it feels to play which makes me less effective. I'm not keen on the hammer either, find it cumbersome.

Any tips to play the class better and/or make it a more enjoyable experience appreciated. I know some people love it but I just can't quite 'get' the Assault class
