Keep lords mitigation is too high, so as all heroes

I hit keep lord for 10-30 damage per hit with full glass char build. Most of lair bosses that was changed by RoR have same issue - they not allow to make usual damage. Because of that some abilities can't be used as they intended (like DoKs life tap abilities) and this is not making game harder, it's just bad craftsmenship. I think it will be better to lower theyre base mitigation stats to usual state and raise HP for a significant amount. This way all abilities of all classes will work correctly.
