DRK changes that would make it really fun to play

[TouchandFeel]

I think that one of the main factors against making HP a resource for DRK that seems to be getting overlooked is simply that it is not encapsulated solely within the control of the DRK themselves.

Damage buffs that players can place on others are very highly controlled, existing within the 2-minute raid buffs, and are that way for the reason of being predictable and more easily measured in terms of the expected output gains which is necessary for proper balancing between jobs and the tuning of content. We can of course debate if 2 minutes is too long of an interval of buff-based burst cycles and whether it should be shorter/longer or stuff like that, but the importance of such buffs being defined to exist within very controlled parameters of availability and frequency is undeniable.

By making HP a resource for DRK to fuel ability usage, you are essentially breaking that above tenet because HP is far more fluid and something other jobs, particularly healers, can at any time and constantly be pumping their resources and effort into, in function allowing healers to pretty much give or deny DRK a dps buff whenever they please. Now the DRK is no longer in full control of their own performance on a moment to moment basis and in order to maximize their individual output, has to rely on other players focusing on them and providing them a constant external source of a resource for them to use. That will just lead to a very frustrating situation. Frustrating for the DRK because they won't feel like they are in control of their own capabilities and game-play, frustrating for the healers because they will be expected to go above and beyond to be constantly feeding the DRK so that they can perform better and immensely frustrating for the developers because this would be incredibly difficult to balance around due to the drastically increased variability of DRK dps performance resulting from this forced interplay.

It's not too hard to come up with various ideas about how to make HP a resource on DRK and it's not too hard to come up with justifications for why your version is good or works, however the sheer level and amount of complications and issues that come with trying to implement this will always make it a hard sell.
