What?! I never knew this! I played back in vanilla and 5 manned all of these dungeons. I played well after 1.12 and had no idea. I don’t think anybody else had any idea either. My guild is shocked! 10 man Deadmines, here we come!
The higher level ones like Scholo, BRD are 5 mans, but all the lower ones can be run with up to 10 people!
Wowhead has info about player caps.
You can clear the dungeon, sure. You’ll get a fraction of the XP you’d get in a five-player group and not be able to complete any of the quests, though.
Originally all of the dungeons were 10 while UBRS and LBRS were 15. In 1.10 they reduced DM, BRD, Strat, Scholo to 5 and UBRS/LBRS to 10
Okay that makes sense. So if we wanted to run it strictly for gear, that would be the way to go. But while leveling and trying to complete quests, that’s a no
Well depending on comp and what gear, 5 might be preferable for gear to reduce competition within the group.
I have a really tight knit guild, so we’re excited for this
Not to mention more competition for any boss drops.
Blizzard actually added dungeon player caps as they added stronger items to boss loot lists, because they didn’t want it easy for players to get those things with what could essentially be zerging. (Imagine gearing your 40-man raid by zerging any dungeon with a player’s BIS until it drops for them, instead of the group breaking up into 5-man groups and spending the hour or two to get to the boss and kill them.)
i kinda remember this but no one ever did the 10 man i don’t know why not
Blackrock spire is 10man, but generally people only take 5 to the lower side. Its quests won’t work in raid.
Since BWL is inside UBRS, how did you get 40 players into BWL (before the attunement orb)?
They nerfed the @#$% out of the high level ones. Voila Patch 1.12.
If you want to run Deadmines strictly for gear, probably the ideal way (assuming other players who will do whatever you want) would be to get a level 60 to run you through it, actually.
I’m trying to remember… I think once you get attuned, you can click the orb to enter. Somehow this is a little fuzzy for me. I remember the window you jump through for MC (since MC is in BRD) very clearly 
BWL is actually outside UBRS, to the right of it and up the hallway, then you click on the orb. Ubrs is instanced, you have to jump through the doorway. This was a good place to PvP also 
I remember a group of people putting together small 10man raids and going through lower level dungeons at the earliest possible levels you could enter them. Like clearing WC at level 9 or something. Funny stuff.
I’m looking forward to seeing how many will fail at jumping that one gap in WC
Oh yes, I remember this too. Muahahaha
You never raided deadmines? It was hilarious back in the day zerging the place with a bunch of low level characters.
I never did it myself, no. I wish I had sounds fun. I have another chance to again though! Yay!
They were 40 man capped until 1.3, then they were 10 (15 for UBRS). They weren’t capped at 5(10) mans for a long time.
