The thing that bugs me is that, level 100 just FEELS final doesn't it?
I've raised a character from 1 to 100, when you say there's a bit of weight to that achievement.
Whereas 105 is...well...fluffy. It's higher than 100 but it's just another number.
Something else, why level 100 for this expansion when the previous expansion relied on increments of five?
Sure, they said 100 was cooler than 95 but we would have reached level 100 at the end of the next expansion...so why the rush?
Maybe they think level 100 is the end of the traditional levels too.
Maybe they're planning something for 7.0, a new way of going about things.
Or maybe it'll be level 105...
