What if DeathKnight had his Aura reduced for less HP regen but all units gained a small HP regen without requiring the aura What if Dks aura was reduced so that it had less healing regeneration, and all standard units gained a small amount of standard regeneration. Would this allow other heroes to be more viable?

Yes we all know blight heals units, but I'm saying what if standard units had a small amount of HP regen off blight, and a higher HP regen on blight? Would it completely ruin the race if Dk aura had less healing regen?

I think this would open up more strategies for UD to start with other heroes besides DK
