spirit link was undeniably broken and the duration change is a good one. The mana cost is a stupid change and basically makes it unplayable.
What I don't understand is how they see the spirit link problem and not the healing touch problem. I'm hoping someone from blizzard reads this and actually understands that something need to be done about druids to balance out the change to spirit link or they are going to rein gods for a long time to come.
Hoping to see druid nerfs this Wednesday but it probably wont happen.
