we gone through burning towns, ancient pyramids, a nexus for magic laylines, a quarry full of scourge slaves, a space ship botanica so what next?
Personally i notice theres a lot of bland empty space between areas, like between mount ironforge and the wetlands theres a large expanse only reachable by flying with nothing but trees. So why not but some 60-85 instances in these hard to reach places? surely its a staple of the rpg to come back to lower level areas later using new skills to find new stuff so why not in wow?
I'd like to see anotehr zul'farak style 'outside' instance, like a dark, foreboding spooky forest. Maybe you have to start escorting one of those gilnean trade caravans through there from badnits and it turns out something much worse is lurking in the woods. Like a small bowl mini one like the ones for the nothtrend drake fights only its a duskwood meets gilneas woodland walled around by dense trees with a winding path leading through a maze of trees, maybe some rest points like a bridge over a little cross section of river or an abandoned rundown in. who knows.
What do you want to see them do, underwater seahorse jousting? a sandbox little island off the coast of tol barad? something in the glade to the right of the undead starting zone? go nuts.
