more tank is more damage!
1) when death you not do damage
2) you can cluster up 4times the amounth of monsters in your AoE damage
3) Damage taken recouped as mana allow more Links, more casts, more Archmage
4) Damage taken triggers cwdt
5) More es turns into more damage with Energy Blade
1 more lvl and i get that juicy 50%damage taken recouped as life, combined with life-recharge
then i can work on my recouped as mana
finaly i can work on the es-heals
soon i gone put on the forbidden rite to trigger cwdt (after mana recoup)
