We also had a shaman who could reincarnate, and also supplement healing while the druid was resurrecting. We barely managed to do it by soulstoning our druid healer and having them just die when they ran out of mana + regen cooldowns, and resurrect via soulstone to restore their mana (no, I'm not joking around here). We did it using 1 tank and 1 healer so we could burst down the dude that mana burns as fast as possible. In particular, the dude that mana burns your healer(s) is a problem. This is hard because you normally have to have 4-5 tanks top keep his adds separated from him.
❌ Fathom Lord Karathress: Possible but only just barely. We had to use 2 tanks and a paladin healer with beacon of light for the 60yd range, allowing us to keep Maulgar away from his adds without using 2 healers. ✅ High King Maulgar: Doable, but difficult. ❓ Chess Event: Not scripted on Azeroth Core at the time so we were unable to attempt it. We were under-geared at the time and never went back to reattempt. I'm a GM so I made a character of every class/spec to fill whatever role we're missing for a given fight. The default setting, 0.5, made 10/25 mans way too easy when scaled down. We use a custom inflection AutoBalance.InflectionPoint setting for 10 and 25 man raids: 0.35, which we've found to be pretty much perfect - at least for the bosses without mechanics that make fights impossible. I'm not 100% sure what can be done about these issue, but I do want to make sure to add my experience here so devs can use it to improve the plugin. I was chatting with and mentioned that many TBC fights were completely impossible to 5-man, even with this mod - he suggested I post them here so the info is not lost.
I use this mod on a server with ~5 players that regularly attend raids.
