According to Henrik on stream 0-80 mastery will take about as much time as 10-20 clade. Before testing, this seems to be TOO FAST. The whole point of adding content like this is to give players a reason to go out into the world, farm and grind tasks/NPCs, explore dungeons, PVP. AND INDEED IT WILL! The patch will drop - player count will rise, dungeons will be filled with players again...... for 1-2 weeks. People will hit 80 mastery and the world will be empty once more. My suggestion is to give us a few fast mastery points (maybe to 20-30 mastery) and make the rest a long grind. Something that might take months to complete. Remember, this is an open world game with no objectives no races no contests. We need long lasting content, we create our own content, and we cannot do that in an empty world.
