I wonder if positionals would be more fun if they were not mandatory. So instead of having to change positionals in your normal rotation you can choose which skill to use depending on the situation. So you would either do a 1-2-3 combo or 1-2-4, skill 3 would do more damage from front/back while 4 does more damage from the flank. 3 and 4 both do the same potency so there is no benefit to using one over the other. Leave it up to the boss to force you around the arena and up to the player to use the appropriate skill according to their forced position. This keeps the intended skill check for the role while not making it feel janky by being forced to move even though the enemy is not moving or doing anything to force you to move.
