If you manage to stun lock baal the battle sequence can take over a full minute, and if it does your toon doesnt run toward baal under the battle sequence flash. it waits for the sequence to resolve before moving to attack again, losing precious time in a race for 1st place. Happens to me often. If a back button was provided you could back out of the lagging sequence, or choose to watch. I believe in this scenario, x2 battle speed may just create more lag issues.
