Traits were removed
The way traits work has been changed in the September 2014 Feature Pack.
You now unlock Adept traits at Level 30, Master traits at Level 60, and Grandmaster traits at Level 80.
You gain 1 trait point at Levels 30, 36, 42, 48, 54 and 60, and 2 trait points at Levels 66, 72, 78 and 80.
If your character has locked traits, you can unlock them by either completing a specific task, or by purchasing them at a class trainer. By default, a new character has no unlocked traits, but characters created before the September 2014 Feature Pack should have most traits unlocked.
