Why is there absolutely no effort or work in obtaining the class defining AF armor? At level45, you basically just have to talk to NPC's, loot bags on the floor, or open random chests in a zone that's of no danger to you. There is no effort involved, it's extremely easy.
The level50 quests are slightly harder, having an actual boss fight, but still incredibly easy.

Why doesn't AF require dungeons? Or party bosses? Why is basically "free" full blue armor upon dinging 45 and 50?

I think AF armor should be an accomplishment, and some actual work involved, would make it more fun. Maybe make the gear a bit more powerful since it would require effort.

Sure AF+1 exists, and actually requires effort and dungeons, but I don't think your class defining armor should be so easily obtained. When every single person is running around in full AF the second they ding 45 and 50, it makes it feel a LOT less special and more generic.
