Seriously you drop it down and it barely heals you. I'm not saying they should be Well of Radiance levels of healing but this hasn't changed since D2 year 1. The Class stat isn't much help because you need it to be ridiculously high to get anything good out of it. Even then it heals so friggin slow! If it could give you a few seconds of really good healing, and then the rest is regular, that would be fine too. The gains from Empowering should be higher as well. This isn't Year 1! Bump it up!
