I love brd. It's a giant underground city with lots of secrets and different themed parts.
The fact that you have options to go different routes makes it even better.
I've spent countless hours in there during classic and gotta say there was a time where i couldnt be asked to go back in there. (Especially after a certain saturday 14hr grind session to get hand of judgement, only for a resto shaman to roll on it and win...)
But now, after a while, i kinda do want to visit it again.
(Maybe if there will be another classic after wrath)
I dont like the streamlined newer dungeons that are designed around the idea of the most optimal route.
They kind of lack something. I dont know how to call it, but it can be seen in revamps like scarlet monastery or sholomance.
They were beautiful creations with so much love put into them.
The new ones just dont feel the same
