I'm rather picky about this, so here are my guidelines:
1. needs to have end game raids. They need to be difficult, or not just stand and hit him at the least.

2. Not heavily pvp based. I like pvp, dont want to spend all end game on it tho.

3. No over powering cash shop. I understand they need to make money, but I don't want to spend more then what I would have with wow on a free to play.

4. If it has a duel class thing, make it interesting.

5. Try to minimize cloned classes. No reson for 2 warriors that do 2 slightly different things. If you want warriors to no differant things, use specs.

6. No huge level cap. Nothing like level 426. Questing helps you to learn your guy, too much questing is just anoying.

7. No grind heavy. Its anoying, takes too long, and I cant stand it.

8. Please let there be instances while leveling. It mixes it up and keeps me from getting board.

9. For the raids, nothing thats requires you too play for 7 hours straight.

10. NO RUNESCAPE!
