The main gripe I've with TBN is that if you actually decide to use it proactively as MT to mit as much damage as possible and figure out exactly where in the fight it's guaranteed to break and where not, you still lose DPS doing it by not pooling all your resources into 2 minute window, comparted to the "correct" use of TBN which is to drop it on a random person during a raidwide before 2 minutes to slide an extra Edge into the burst window. I'm not going to suggest specific changes since nobody cares and Square doesn't read this, but if DRK has to have dps and mitigation tied together, that relationship should be reversed: give us better mitigation for doing dps correctly instead of punishing dps for mitigating better.
