Guild Wars 2

I feel the mastery system was not easy to understand. It could use a bit more work to make it clear and easier to use.

I agree with the op, from what I could see it only shows you the mastery points you have ever earned, and not how many you have to spend.
Example you could have earned 4 in your lifetime, spent 3 of them, but nothing is telling you that you still have 1 point to spend (unless I missed that).

Also I think at one point I even grinded a level of xp with no mastery selected, which I think was just wasted. There should be some auto select mastery like there is with pvp reward tracks.
