New player.. What is different between WOTLK and WOTLK old?

[Bookibaloush]

Can you play with players in between WOTLK and WOTLK old? Which one is more populated?

[AttysuthePoro]

It's the same thing, but 'old' is just WoTLK models. 'new' is the WoD updated models.

Yeah it's rather confusing to call it WOTLK old, just call it WOTLK and WOTLK Wod models.
