I fail to see which open world content GW2 has that this game hasn't, apart from jumping puzzles. Let's see:
Here main story quests <-> GW2 main story quests
Here class quests <-> GW2 nothing
Here side quests <-> GW2 "hearts"
Here FATEs <-> GW2 "dynamic events"
Here levequests <-> GW2 nothing
Here dailies <-> GW2 nothing
Here treasure hunts <-> GW2 nothing
So, I'm sorry, but FF14 ARR wins on BOTH open world and instanced content, PvE-wise. GW2 wins on PvP (not surprising, as it's the main focus of the game), but PvP in GW2 is instanced anyway.
What's paradoxical is that this game has the MOST types of PvE content I have ever seen. The sheer quantity is not so impressive yet, but give it some time, can't compare with games that have already several expansions under their belt!
