I think the same. Non NBs are happy, till they get ganked by some broken Necro / Warden / Templar / Sorc / DK Vampire combo. Cost increase for non-vampire skill does not matter much if you are ganking
This will make class balancing even worse. Sorcerer DPS is weak and will be even weaker. At the same time MagDK which is ahead of Sorc for PVE got a tremendous buff by increasing the value of Asylum S
I tested it on pts and I can assure you sustain feels much better on magdk , intellect buff solves sustain problem of dk and I will switch back to magdk for sure .
