I dont see why anyone would want old runes back....Old presences? Sure, DK prob has the worst defensives in the game, Our warrior (who is pretty inept) dies far less than me to passive damage/AoE healing phases, AMS 90% of the time needs to be saved to immune something or clear something so its not really even a defensive this tier in pve, its a straight dps cooldown. IBF is the largest pieces of trash CD in the game, and should be 1min CD in pve. Having blood presence back would change this alot.
Old runes though? No reason.
