I've yet to play one of the stealth classes, but I'm sure that helps alot sneaking around and all. One thing to consider though, Most every quest has a "bonus" part of it that has you killing the aforementioned trash mobs. Doing those bonus quests generally nabs you three extra planet commendations per mission which goes a long way in gearing up all those orange armors we all like so much. You can totally skip the bonus missions, but as a solo slinging sabotuer I'd rather lob a few nades and spend an extra few minutes blowing things up than sneaking past it all. I'm just saying...
