[Suggestion] HOT Mastery Points
The mistake that we will gain mastery points from leveling up comes up now and again.. This comes from a misunderstanding in how the mastery system works. There are two components to masteries: 1) mastery points and 2) xp. Mastery points are gained from various activities (such as map completion and adventures). Mastery points unlock a ‘tier’ of a mastery and then that ‘tier’ has to filled via xp. Thus you can’t level masteries using xp alone.
Besides that, Anet has stated that they are still looking at how leveling items will work with the mastery system.
