Please specify the MMORPG or MMORPGs and when you last participated in a raid in that game.
As for myself, I soloed (with an NPC Mercenary) several lower level raids in Everquest 2. I think I started doing it when my character was lvl 90 (back in 2014). But I would mentor down to an appropriate level (5 levels higher than the level of the raid, so I could still get loot). Did a couple lower level raids with a handful or less of friends/acquaintances and guild members also. Actually, I did participate in one large raid in Runes of Magic. And I think I remember that one player's mistake could cause everyone to fail. It might have been a 50-man raid, but I don't quite remember. Been a long time (2008).
EDIT: Oh, also, I played some high level dungeons in Neverwinter that sometimes felt like Raid difficulty (even though they only allowed 5-player groups)). This was especially the case right after Module 6: Elemental Evil was released back in April of 2015. Though, of course, any content in a game can be very difficult if player characters don't have the proper power-level of gear for it. In games that are very gear-dependent for power anyway.
