Greetings Devs and other excitable keyboard designers.
One of my first builds when I started playing asension was to try and make the vampirism epic Re and improved vampiric embrace Rare RE's to work with a bleed heavy AGI character. While it was fun, it wasn't very good at doing either of the things it really set out to do, be hard to kill with good sustain from your lifesteal effects via your bleeds, or do good damage as a mainly rogue/warrior hybrid relying on damage over time to kill your enemies.
With the addition of the two most recent alternative healer RE's that are inspired by traditionally dps spells and builds, I would love to suggest another that uses the bleed toolkits in the game to heal your party. A legendary RE that increased the healing of bleed specific vampiric embrace healing on your team.
Below is a list of ways I think you could go about it, but I want to stress that there are likely many ways to do it successfully, and really hope the Dev's like the idea enough to either pick and choose from the list below and/or add their own :D. The three things below are how I would personally make the new RE, if you have ideas of your own and like the concept, please comment!
1: Legendary RE component: Upgrade a buff spell to act as a "target" that increases the bleed healing specifically on that player. This I think is crucial to making it viable in dungeons and raids, but having it be the one character and being able to swap it I think creates interesting gameplay. If I had to pick a spell I personally would pick [Power Word: Shield]. This could involve similar debuff's that exist currently (not being able to cast it on the same person with X seconds) but could also be worded that the heals from the casters bleeds heal this shield as well. So if you cast it while you have full bleeds up on someone/something then you get a longer duration out of it unless they are chunked by a larger ability.
2: Legendary RE component: Having played the bleed build for a while, I think you might want something to replace Blood and Guts (which was my legendary of choice for my own dps bleed build.) I think I would upgrade hemorrhage to become your main resource dump/builder for this archetype, and make it so that the debuff applied not only increase damage per stack, but also increases the healing you do via your bleeds by X amount per stack.
3: Legendary RE component: You can use the cat or bear form bleed builders and spenders even while not in those forms. (You would still need to purchase the abilities, but you wouldn't need the forms to use them with this RE.)
