- I dont have any particular opinion on that. Would surely be a pain to not fly, but with so little world Content there shouldn´t be much of a Problem. Most of the Time you either Run Circles in a High end Zone for Professions, or run an Instance.
- As Others Mentioned, BGs where a thing in Vanilla.
- Kind of split on that one. For one, I like questing. On the Other hand, I have a rather good memory in that regard, will probably remember most of the stuff, and then its Boring.
- Weapon Skills, I dunno if I would be Hyped about them. Was a Pain to level them all up.
- i seriously doubt you would get much or even any "WTF happend?" moments. Because for
A: People already should know how classes/specs work in Vanilla.
B: Unlike Vanilla there is already large Community providing indepth analysis for stuff. Most people immediatly run the single best Spec.
- See the above, while I would be more invested in reading Quests, I probably would still know much.
- Talent Tress, the Illusion of Choice. See Above, I think there would still only be one Specc Viable, with little room to Customize.
- Skill levels are just a GoldSink, dunno what they add for you, except a forced way to run back to the Capital to learn skills every two levels.
