As per the title, the effective durability afforded by a good healer with a good build still feels a little over the top. I realize there are counters to it, but I feel like the overwhelming majority of my build and gameplay decisions often end up revolving around trying to deal with the enemy healers.
I'm not sure what I'd prefer to see done about the situation- mostly just expressing my observation that healing (and the countering there-off) still seems to dominate the game a good bit.
Perhaps lowering the speed of in-combat healing but raising the speed of out-of-combat healing would help. Alternatively, adding an incoming heal reduction or block to either the drain or disruption effects would increase the counter options for in-combat healing.
