Yeah, you'll want click-to-move/interact. Once you set it up, you just have your melee toons assist you, hit the interact button {I have 1 set up for all toons for quests/refacing in combat and one just for melee so the casters don't try to come running}. Your melee toons will then run up to the target on their own to start attacking. But I keep my melee-only follow button handy because sometimes they seem to think "interact" means "run by and whack the mob once before running off into the sunset".
