I actually started with Cata, and am only now umm..."looking into"...the Lich King expansion.

hint hint, wink wonk

It might just be because it was the expansion that I started with, but holy dingus old Orgrimmar is hard to navigate! Blimp towers outside, the warchief in...I want to say Honor? Instead of Strength...Not sure how much Stormwind changed, but it looks about the same with a few minor differences to how it is today.

It really changed a lot from WotLK to Cata...I can see why people would've been upset o-o. But in regards to the casualization, I believe there's a particular mindset that people don't want to grind out levels like they used to, especially if they're paying monthly for a game that keeps increasing its level cap.

They gotta get, and keep getting, that phat muns somehow. Enticing new players seems to be the choice they made in that regard =/
