Core Tyria mastery points
Yes. There are no mastery challenges or channel spots in core Tyria. There are a lot of achievements that give them though. When I logged in on day one of HoT I already had over 35 core Tyria points unlocked and I have only been playing since January of this year.
It’s meant to take some time. Find a group of friends or guildies and go hunting for them. I’m not entirely sure what unlocks all of them, but there are a lot of achievements that are fairly easy to get.
