What a HUGE disappointment to find that the level 51 CM ability "Unholy Bond" does NOT stack with any other heals, not even Necs. So, if you pull a REALLY tough mob or you get adds and think that Unholy Bond is going to save your *** - it won't. It will cover up any heals lower than it does but it will not stack. So when your heatlh bar gets to one red bubble and you already have a heal on you from your healer, that's all you're gettin as far as a heal is concerned. The damage it does will help of course, just better hope the damange it does kills the mob before you die!
The only time this CM is good for anything is solo'ing (which I don't do) or Dueling. Or, if your healer dies, which is all your fault anyway as the tank! :-)
It's 1 hour recast makes it useless for really solo'ing. As far as a duel is concerned, you won't be up for a sure fire victory at least for another hour. This along with not stacking, makes it unworthy of the time it takes to get the CM's - IMO.
