Build recommendation?

Hello, I've really enjoyed playing with arc but I was hoping to switch it up a bit and try something else. I'm a pretty casual player and am looking for something fast and fun that can hopefully clear endgame bosses without a ton of investment.

Any suggestions for a favorite build? What do you have the most fun with?

Earthshatter Berserker seems pretty popular at the moment. If you're playing SC maybe go for something a bit more adventurous, but I think it would fit the description you are giving, though maybe not zoomy enough if your wanting it to be fast.

Kinetic blast is a build i'd like to try out but haven't got round to playing yet.

Berserker all the way - cheap and effective. Or you can check "the guide" which is apparently so awesome it makes everyone want to play RF
