Long and creative combos I guess? Was looking at Monk and Rouge, though maybe Shadow Dancer is cool too.
Game has a Priest class
Kunoichi is the most creative class in the game.
If you want combos, Rogue would have been it before she got reworked I think, but that's just hearsay honestly. Some Rogue mains were not satisifed with it. SD, not really combos I would say, just knowing how/when you can get behind enemies to activate your Shadow Dancing and do full damage. Still fun though.

Can't say I play either of those classes but from what I hear both of them are in a good spot right now and they do fit the playstyle you suggested. You can make two characters a day so making both to try them out is reasonable to get you through the naming screen. Shadow dancer is a bit different from them since it's main gimmick is back stabs and plays like a grappler at time but she is really fun and some of the animations are really satisfying to watch
Is there a guild that people are in? Picked Thief and was hoping to play with some people.
