I was thinking, in regards to how this game gates everything behind the main story, how is the expansion going to work for new players who hit level 50 after the expansion comes?

Are they going to have to do all the primal fights that no one will be queueing for anymore still? Or will all the 50 quests (that don't even give experience) be made optional content?

I really hope it's the latter. I can picture a lot of people being really irritated if they can't play the expansion without lots of needless catchup in all the level 50 content that they missed with hour long queues at every turn. Just some thoughts.
