I kind of hope they don't raise the level cap too soon. The problem I have with raising the level cap (If done WoW-style) is that a ton of gear and content instantly becomes obsolete. I almost am tempted to say that the level cap should be gated behind some kind of content & quest that requires say iLvL 80-90 so you have to spend some time on the current level 50 content before moving onto 50+ content. Until you complete that quest you can't level past 50. Otherwise future new players will just be trying to skip all of the current 50 content as fast as they can in the future. They shouldn't need to spend months on it as we have but it would be nice to have it still have a reason for existing in the future. It's one thing I really don't like about WoW.
