A lot of people say their school suffered cause of WoW, but for me it was Oblivion. I put some crazy hours into this game.
Having said that, it was jank, just super jank. If you were to play it today, you would either be extremely amused or annoyed by it breaking constantly in some way.
If it's a full on remake, they sure have their work cut out for them.
All the things I wish they would fix include:
Super wonky AI.
A radiant dialogue system between NPCs that is bunch of nonsense almost always.
You having to follow NPCs during certain quests as they walk super slow and might get mauled an killed by a random enemy along the way.
The entire game being voiced by 10 people.
The combat feeling like you swing around a wet noodle.
An enemy scaling system where at higher levels a normal goblin takes 15 minutes to kill.
A level up system where too many things can break, such as stacking the athletics skill to the point that either the game crashes or your character just dies from a "fall".
Or they could just give it a face lift and let everyone suffer through it as it is.
