Guild Wars 2

Good morning all. I have been a casual on and off GW2 player for a while now and recently started leveling a Warrior. I noticed that traits had certain events that would unlock them so that players that were low on skill points or currency could acquire them in a cheaper and more fulfilling way (IMO). But for the life of me, I can not figure out why adept traits are in areas as high kitten-65 level zones. Does this not make since to anyone other than me. It just seems like the possibility to unlock traits should have a zone and task that corresponds to the tier that the trait is in.

I just recently hit 80 and wanted to start unlocking some traits. After going into eternal battlegrounds and neutralizing Orgath Uplands, I stood there nearly an hour waiting for the event to start and it never happened. Am I missing something, are there other things that have to be done prior? I have googled and searched and still cant find anything on how long it takes or why it may not be starting.
