What good Dash combos are out there?

Republic with GOWK or darkwoman light tutor+quigon jedi master, Padme (Snowbunny), I know this might sound funny but Commander Ahsoka, because of Dash's high damage output, if he's adjacent to somebody he could then use rolling cleave to twin to his next target, of course if he's going to be engaging then you might want to think of putting him with General Skywalker to benefit from the momentum.

Imperial-Lord vader+dash. or Emperor on chair+dash to allow him to reroll on his attacks or movement, thrawn of course for the ability to swap him in.

Anything/anybody that gives him accurate shot is also nice.

He's very versatile, his low atk is what hinders him, but with him getting 4 shots guranteed everytime he attacks and the possibility of him doing 80 damage alone without any commander affects makes him dangerous. He doesn't necessarily need CE's to be great, as long as he's not your main piece. The longer you can keep him alive, the better because his ability to come in and shoot and kill activations as well as do heavy damage makes him very viable to have in the later rounds.
