Idea for a penalty if you all really want one.

1. 75% Movement speed reduction.
2. Blood Rite effect
3. All Abilities used in weakness become 10 Minute cool-downs.
4. Anima cost returning upon death -10 Anima cost.
5. All stats reduced to 1 underweakness.
6. Enmity greatly increased when near an engaged enemy over time.

This will make zerging hard, and death warping negated.

With the blood rite effect if you have 100 hp and you attack the mob, you'll lose 10 hp. If you have 10 hp left and you attack again, boom your dead again even if the mob doesn't attack. If you're bleeding a lot and you move around, what happens, you make the injury worse.

Making cooldown last longer when weakened, will definitely keep anyone from zerging a monster. And with stats reduced to one why bother attack anyway. Just by standing near the mob it will know you're weak and will want to kill you, so after standing near it long enough it will turn towards you even if the tank has had hate for a while.
