Proposing New DRK Change

The recent live letter excites me for the upcoming change to DRK. It is also in this excitement that I hope to see some common ground change that balance between our community comments and Devs idea behind DRK. As such, I would like to propose some QOA change to DRK in no particular order:

1) Please bring blood weapon to 5 stacks system like requiescat. It reduce burden on players with ping issue and allow 5 AOEs in dungeon. 5 AOEs blood weapon in dungeon will not imbalance this class in my humble opinion.
2) Bring back Abysmal drain independent ablility from Carve and spit. Potency can be adjust accordingly. This allows DRK players do not contemplate between more DPS or heals. Also it will help healing DRK further since it's currently the worse sustain tank in Dungeon.
3) Remove Salted Earth button and added the trait in abysmal drain. For enemies that abysmal hits, it will DOT them as well.
4) In level 86, allow two charge of Abysmal drain. Or allow us to combo abysmal drain, like salted earth, that explode and heal us again from the first enemy that the ability hits.
5) Make oblation an upgrade to TBN that allows two, or three stacks, of shield. Shield at the second stack, and third, can be less potency than the first one. So maybe 25->15->10. Maybe let it heal us at the expire time if not break.
6) Remove TBN cost and increase CD timer accordingly.
7) Make shadowbringer as an upgrade of flood of shadow and add the single target upgrade accordingly with potency adjust. Currently shadowbringer is just another button that does not feel substantial to press. It also make DRK feels bloat.
8) Bonus: make Dark mind a 15 percent mitigation.

If there's anything from recent live letter we can take out, is Devs listen to us and try their best to accommodate our needs. Please be respectful and continue to constructively criticize until we get the best version of your favorite class.
