Playing the game as a classical support character feels unfeasible on nightmare difficulty, the amount of damage taken and trade off in dps you get for taking multiple support spells really make it a not a viable playstyle. Even with low cooldown builds on spells you are better off taking more horde clear than damage prevention like doll or recovery like ritual. I wish voodoo spells did something other than just mitigate damage. maybe gave a buff to allies as well so that death spirals are less likely to happen as a trade off having lower overall dps compared to other characters. I feel like with better supporting spells the game would be benefit a lot.
Ideas for a buff on rescue drain and ritual would be something like a % damage reduction for the next few seconds after being targeted by the spell.
On doll maybe a damage buff to those inside the area.
Any other ideas would be nice too I just would like something extra as it just feels kinda pointless to pick anything other than rescue as the game stands now.
