Those proposed changes would just make DRK weaker, so I'm gonna say no.

Sole Survivor would be welcomed back, I'd personally make it an Excog equivalent (since that's sort of what it was in the first place) where it automatically procs the heal after reaching a certain HP threshold or the timer going out instead of after killing the mob, but nerfing TBN and Blood Weapon are bad. Why does everyone bringing up DRK suggestions think TBN needs to be nerfed for DRK to get buffs, it's a good CD but not ridiculously overpowered.
