I think my verdict is...

I love the kit and how it works together and it makes for interesting healer play and so far I've felt like a shield healer again, which was missed and DPS variety has been frequent enough to not kill my experience so far. I'd not change much of its kit so far and it feels closer to what SCH should have been in 5.0 and definitely is a step in the right direction.

I think Toxicon suffers too much at single target situations and means I Dosis spam more. And my concern is the lesser healing requirements get, the bigger of an issue this will be. Fortunately in an AoE situation, it's more often or not a DPS gain regardless of whether more efficient healing methods are available. If this experience is transferred to single target, you'll make DPS more engaging and people can complain less that healers aren't healing, because it has been incentivized.

If incoming damage is strong and frequent enough it's not an issue I think because you legitimately have a reason to put a shield up and there is a mobility benefit to using Toxicon still. But healing requirements will go down. Maybe it could be bigger damage for the first enemy only. I know there is some saying make it an oGCD...my self include, but I wonder if would make it more like Energy Drain in terms of feel/flow and I don't want that.

I feel like where healing requirements go down is where we will suffer again...but I think out of the healer jobs, we're in the best position alongside AST for dealing with the monotony...depending on how frequently we can get Toxicon without it being a DPS loss.
