I don't know if this was allready reported so I'm doing it now.
It occures inside instances as far as I know.
If you die as mystic, you notice that your thrall aura is still shown as active in your skill bar.
Your buffs show: not active...
So basically, you have to disable it first (that's what the first press of the binding will do) and then you have to reactivate it.
This is sometimes very furstrating, especially if you're doing new dungeons like today and then you forget about it in some situations and then end up with a useless heal thrall and lots of cd on it.
I thought this will get fixed with patch 98 but well...not the case.
Maybe noone reported it...
