I know blizzard has said that they want to make BFA raids soloable after 10.1.5 releases.
Im here to ask blizz if they could also take a look at some of the other old raids.
Im thinking about Tomb of Sargeras to give an example. The Desolate Host sometimes bugs out and remains uncompletable for quite a while (1 hour ish last time I tried). Your character can even get stuck here waiting for the fight to end.
AQ40, specifically Viscidus is also quite hard to solo if you cant deal frost damage / auto attack very fast.
Ulduar also seems like it could use some love after timewalking was introduced. Loot seems very random and unintuitive with 10 and 25 dropping no matter the assigned raid difficulty. Sometimes hardmode caches drop an extra item, sometimes nothing. Ive also learned that to complete my ulduar 10 man tier set I will have to go grind mobs in Warlods of Dreanor for a rare drop, which makes no sense at all.
Sometimes the mobs before Thorim keeps respawning delaying the start of the encounter, idk why this happens. Mimiron remains untargetable for a little while after he starts attacking.
As far as Im aware firelands do not have the same problems, but I might be wrong. And I also might have missed a few old bugged raids. Pls fix blizz:)
