I know there is a lot to do whenever it is in dungeon or in raids
This post may be serious, or a rant, or a bait, who knows in this forum.
But there is just one thing i might ask.

Could we maybe have less :
"Boss auto teleports in the middle of the arena every 15/20 seconds"
And more of that positioning job coming from the tank?

(i mean positionning, not just moving to evade AOE or doing mechanic which is still nice)
(maybe nor the right MMO to ask, or the fight design doesn't allow it, or any other reason, but the "auto teleport" just feels ankward to witness every time for me even after all these years)
