Hello!
I noticed with Wield Soul (Leashing Soul) that it does not apply a taunt if one is already applied - that is all well and good, as we wouldn't want someone to use it to steal aggro from a dedicated tank.
However, I *also* noticed that it does not refresh it's *own* already applied taunt (since it does not reapply, given that the target has already been taunted). This means it is possible to lose aggro if the reapplication isn't timed *perfectly* between the Boss's next attack and the expiration of the prior taunt.
If that is intentional, I question why it should taunt at all - if it is impossible to refresh the taunt without potentially losing aggro, this means that it may be better to have *pull then immobilize* rather than *pull then taunt*. Otherwise it deceives people into believing it is a true taunt skill, but they can lose aggro since they can't refresh he taunt.
