It is extremely incohesive to attach a heal to TBN though. The idea with TBN is that you can use it at full hp so if you have a heal placed on the beginning of TBN you just overheal and achieve very little use . Wouldn't it be better to put healing on a different skill all together? Like putting one on Oblation instead of TBN? I love the idea of healing based on damage taken since WAR heals when doing damage, PLD heals over time, and GNB heals a large chunk with their on demand cooldowns, so healing when taking damage is that bit of flavor DRK could use to keep its identity separate from the rest. I'm just not so sure TBN is where it should be since it could very easily result in overheal and very frequently not even taking full advantage of the healing effect. Usually you want healing after shielding is consumed.
