I miss a lot of the stuff that made it feel like a real world, instead of a game.
First time I travelled to ironforge to learn to use axes or whatever. It felt like I was seeking out some old master, the only one of his kind to teach my how to use a weapon.
Bows and quivers and the like. Annoying for sure, but it felt like an actual world. Plus you could see the quiver on your character model.
Going to your trainer to learn to skills.
Quests that actually took you around the world instead of on a linear zone by zone path.
I miss the adventure...it's turned into an arcade game.
