- Your Icecrown Citadel raid and 5-man content, and the Wrathgate chain, have some distinct differences depending upon what side you're playing for.
- Each starting zone has its own unique flavor, and causes you to look through that zone with a whole new lense.
- Cataclysm is going to bring significant changes to much of the old world content, so if you don't do it now, you may never have the opportunity to see many of the places/do many of the quests that tell the old stories of the scourge.
- The other side has better candy.
- You just might make some new friends who will help your future worgen/goblin alt steamroll through leveling post-Cataclysm.
P.S. I didn't make Jaina cry. She was crying when I got there! You have no proof of these foul accusations!
