TL;DR all the posts.
But i, personaly rerolled from DPS Operative, to Marauder and now i can carry the ball if i need to score my daily BGs.I can play passes with my mate assassin, because he is good at scoring the ball too, even not tank specced, he can run fast, especialy if my predation is up too.
I tried to be useful on my Operative on huttball too, but i tired trying, all i can do there is gank ppl that running around alone, but republic on our server usualy stuck in blob around the ball, spaming healing, guarding carriers etc even in PUG.
So they cross to our side with blob, then i always got knockback to pit with my operative and i cant even dps on the ball after, because i dont have any gap closer.
Juggs are easier with scoring the ball with their 20sec cd defensive jump, they can jump even on stealth temmates, that can sneak around the score line.
