You are giving up stats to get the healing from the 4 piece though, so it is taking away from a different source. The main argument was about whether giving up the proc is worth the stats you lose. I just prefer to have stronger shields than a proc that may be wasted. I admit it also may not be, I just rather have mor control over it.I think you're missing the point. It's healing that you wouldn't otherwise have. It's bonus healing. It may come with you don't need it. But it should be consistent enough that enough of the healing procs hit when they are needed.
