I think what you are really asking for is for the Warlock Skill 'Shield of Solid Mind" to be based off of something other than Healing Bonus in order to be a useful skill. That or reduce it's cost. In other words, you feel that for it's cost it should do more, or if that is all it does, it should cost less. Or, just re-word the skill to say that it prevents 1/2 your Matt damage. Personally I find that it does an adequate job, not very exciting, but not useless. The cost bothers me a little bit, but for what I use it for, not that big a deal. I just wish it absorbed the bleeds in the new continent like it does in all the others.
