So you're telling me..

Their hot affects everybody around them. In full parties grouped up, it was a lot of extra heals.

I really don't think it's going to affect much at 50 potency loss. If anything it's going to give healers something to heal which is warranted.

I think the nerf is reasonable given that being tickled pops the shield. 50 potency heals are very reasonable for a 30s CD.
