Please name a boss that randomizes its attacks in this fashion.
+/- tethers may interrupt your rotation, but it doesn’t change the rotation. If you have to disengage for a -/- or +/+ repelling tether, you simply lose GCDs. You don’t suddenly alter what you’re doing.If you get tethered your rotation is screwed depending on the type of tether. If its the one where you have to turn around to stop the thing tethered to you from following you or burn the add attached to you, you're going to have to totally change up what you were going to do next, you can't face the boss mob anymore and now you have to burn down the thing attached to you. If its the type of tether where you have to run in the opposite direction of the person your tethered to to break it... you're not going to be able to complete what it is you were trying to do. If its the positive/negative, or positive positive tether, your rotation is going to be disrupted when you get sent flying in one direction or the other.
