Biggest Change: no mechanics
Definitely looking forward to the "old version" of dungeons. Ran through Sunken Temple the other day, such a disappointment how fast/easy the dungeons are now.*Thanks for putting this together!
Lol, my first time in wailing caverns was ~2 hrs or so... we kept getting lost and going in circles...
I don't see any mention of much faster dungeon trash respawns. I think that will be the biggest shock to players who have never really had to deal with that before. An late-run wipe could doom a dungeon run when half the group drop out rather than reclear all the trash just to get back to the last boss or two.
You forgot the 5 player cap on Dire Maul, and you have Zul'Gurub included in this list when it is a 20-man raid in Classic.
People being offended with Classic Dungeons having no big mechanics is 10/10.Classic has other big features, you knew what you asked for, move on.
