I will never understand, why people who love to Focus on ONE class and Endgame-Raiding only... play new MMOs.

Is the "I was one of the first" so much more important compared to having content?

If you want to have a big endgame content, join a MMO that is >1 Year after release. You have less bugs, more features and more content.

New MMOs will never ever satisfy you - and you should know that by now. How often do you have to make the same mistake over and over again until you notice that?
