What should happen?
The red and the green ooze should target a different player each, never both on the same player!
So the red target can kite the ooze, while the green one targets another so we're able to kill green, without red coming to the same player that is stuck and wiping raid-
What do you see instead?
When the red and green ooze spawn they both target the same player, making the fight almost impossble in hc mode. Since the person that gets red is suppose to kite the red one, but is stuck due to the green also targetting him.
Well not always the first time, but always ends up after a few times if not the first time!
And it can happen several times in a row.
