Im not making light of the lack of anything behind the wall, apparently a dev actually mentioned they forgot Gilneas existed while they were planning the next expansion.
Okay that’s funny if true.
I remember breaking into Gilneas once, its mostly unrendered terrain but theres a few farms for decoration to see while your flying. It was also much smaller, it didn’t extend as far west as it does today, and you couldn’t see it from the Wetlands.
