I was also kind of wondering about a professions revamp but I would imagine they would save that for a future expansion. I really enjoy the discovery tab that guild wars has for its professions, but that is a lot of revamping on their part and may not be worth the effort given the lack of variety we have in game and the true necessity of the feature. But I'm still hoping for the event system. It really is a unique feature to guild wars and would definitely help draw people out into the world. The only issue would be the level differences between characters, but if they found a way to normalize character levels like they do in guild wars, ontop of the cross realm zones and events, it would essentially revitalize all previous content for new players and even veterans that never explored the revamped cata azeroth.

It isn't, but you see how may people it draws to the events! And you see how fast people will march out to those bosses for a chance at their random exotics or rares! With them adding a new color loot, it makes me wonder! ******* Also, more speculation - the meteors randomly hitting parts of Azeroth in Wrathion's vision? It just seems like that was building up to something more than just, "the legion is coming!" And given the demand some people have made about wanting world events like the elemental invasion, with the contradictory complaints of them destroying everything due to level imbalance, it would be a good neutral ground to fall back on if they balanced it similarly to guild wars.
