The thrall taunt perk should be moved to a perk location where it is a choice rather than a requirement. Just because a player wants to focus on thralls does not mean they must want the thrall to taunt. If a player wants to play the tank character having their thralls taunt messes everything up. For example, play as a tank but have say two archers as support. The archers will pull all agro and die instantly while you as the tank can do nothing about it.
Thrall taunt is a much needed addition for some playstyles but having it a) mandatory and b) the first perk completely takes choice away from the players.
