Merc is all you need for support lol
but yes d2 is all socially awkward ppl that can’t team play unless someone like mrllama pays you to join his ladder reset squad
Jymnasium has been running D2R 8 man speedruns pretty regularly. They are nice to see. And they pushed it really far. (Oftentimes Teo and Mekalb would join too, aswell as other less known players/non streamers).
Even then, you'd have some kinda supportive pals, but they remain somewhat always DPS.
Like there is the Leap/BO Barb and Druid but I meant like an actual Healer using Holy Bolt + Cleansing or something.
The 3 pals trio would have 1 Conc, 1 Med 1 Salv I think, so it is really about the trio, but even then, the Med and Salv remain Hammers once lvl 18, and they are more QoL than really supports.
I get that DPS is what you want, but well, IDK, I guess I should go and try WoW which I know has actual Tank/DPS/Healers with DPSMeters and Healmeters... And real Healers. Meh.
I'll keep on dreaming about my healer pala
