LBs really could use some work, and I think you've got the beginnings of a really good idea, Pterois. They'd have to be heavily nerfed for DPS classes, and some strategies that involve mage LBs would either require multiple mages or be scrapped entirely.

Still, I think it could be the start of something that would have potential, and as a WHM main I know I'd love to be able to use an LB every once in a while. Let me throw out a Stoneskin that's the equivalent of 100% of someone's total HP, something like that.
