It is not good for soloing at 60 It heals for the same number now as it did at 50, even though our HP totals have doubled. Healing for 400-600HP when your HP is 5-6k like it was at 50, that's just enough to be decent, and just enough to help keep titan up. Healing for 400-600HP when your HP total is over 10,000 is not.
At 50, that 400-600HP cure was enough to offset that DoT, or that auto attack. At 60, both those DoT's and auto attacks from mobs also went up as HP totals did. Thus making it useless.
