With Epic Elite mobs having Uber hitpoints it seems that some of the death feats such as vorpal strikes (weapon and feat) seem pretty obsolete if you run mainly EE content. Im looking at my feats list for vorpal strikes and am considering replacing it since it procs on a vorpal 20 when enemy is under 1000HP. To me its not a big deal since 1000Hp is only a second or two more of dps. The extra 100 dmg on vorpals when above 1000HP is okay, but in the end it only adds somewhere between 200-700 extra dmg. To me not worth it for the slot..
What do you guys think?
