Oh should just mention this for NON-TANK players, since I noticed some didn't know and got pissed off at the tank...
Bosses uses moves that targets random players time to time even if the tank has 100% hate, it's not the tanks fault or anything... If you're not the tank and see the hate list and it's flashing red (like Zfz's image above) then something is wrong with the Tank, but if it's not then it's that bosses random move so it's your responsibility to dodge those moves.

Had one noob getting all pissed off over this one and everyone else in PT was trying to explain and he/she didn't want to listen and just left LOL
