OK I think I didnt make myself clear last time, I will re-post it again.
The new change of the Pop Boss is actually Turbine's Devs exploiting the system bug.
For now, we players can only target an enemy by hitting tab key to cycle through ALL the enemies in the field through to find out what target we want. That is one of the reason why we want to encircle that Warforge boss and keep him from running around.
But now he can teleport.
Teleport is ok, I understand even monsters must have their own right to earn a chance to survive. But Turbine you must understand, when that boss teleport, he can BREAK the TARGET LOCK we put on him! He will disappear from focus orb, hide in plain sight, and launch his vicious attack toward us while our players try to tab through all the minions to find him again! And when we finally target on him again, he teleports away, break the focus orb lock, and we have to tab through all those s**ts on the field to find him again!
Isn't this Turbine try to exploit the system bug? Try to exploit the bug in system design to gain advantage for their own?
1. Fix the focus orb bug, make it maintain FOCUS on the selected target until we player hit the tab again to focus on another target.
2. Remove that stupid warforge's ability to teleport!
How inspiring, Turbine ask us not to exploit the bugs of system and they exploit the bug themselves!
