Shattered Kingdoms

Cyra, do you mean a hellion who isn't fighting can jump into the middle of another fight with a cleave(This I am very well aware you can do, which is why most hellions have auto assist off), or are you saying a hellion who is already hitting/getting hit can use the cleave command to do the cleave attack(I'm preeeettttyyyy sure this isn't possible and isn't what you mean, and I figured this is what Kin meant by making it so you could do it in combat)?

You could always abuse the disconnect bug.
