I love just about everything about this, except two things concern me

"Party/content matching for players from different World servers"

I really hope this doesn't become the only thing 75% of the people in the game do, people standing in their estates or at the repair NPC and just using Dungeon Finder all day, its so antisocial with your server/world, and while its great to be able to find people for dungeons quickly and easily I'm not sure if it outweighs those negatives.

"Jobs to progress by clearing quests rather than gaining EXP."

I think I might need more info on this but I thought the jobs would be similar to advanced jobs from 11? That you unlock them and start at level 1 and exp them to level cap, more details would have to be released but it almost sounds like that jobs are some kind of addon skills for classes currently in place.
