I would in all honesty recommend a BA if you like the RK play-style as its honestly the closest equivalent when it comes to bottom heavy burst down damage.
Problem is though, as it is with all creep classes, is you wont be much use till you gain sufficient ranks in order to acquire certain skills; or until you buy skills from the store.
Getting used to the 40m range will be new aswell.
And as usual, expect to die horribly and often.
