Guild Wars 2

Right now, there isn’t a lot of use for XP once you complete your Masteries (or any use, if you’re stuck behind the raid lock and doing HoT/LS3 content, or just out of Mastery Points for a while).

It would be nice if each Mastery was associated with a thematically appropriate reward track, structured like PvP and WvW reward tracks, and advancing using XP. That way, once you unlock the final tier of the Mastery, you could continue to put XP into that Mastery and receive something more interesting than a Spirit Shard (although, each track should probably disburse some Spirit Shards as well).

I like the idea of using xp for more than just getting spirit shards, but you are already well rewarded with items by playing through PvE. I worry about making PvE too rewarding for too little effort, or that consequently these reward tracks would be so underwhelming that it wouldn’t make a difference at all in people caring about gathering xp.
