I remember this being an issue before with unarmored, but for example.. I'm a Dullahan with at least 20 levels in Archer and have it as my main class, wearing a Roughspan Tunic, am using a Bow in my Main Hand, and won a fight versus various enemies.

It didn't unlock Ranger for me, but funnily enough it did unlock Arbalest, because of the whole 'always considered to be wearing heavy armor' thing.
I imagine this is a bug since I think you're suppolsed to still be able to unlock them, i'd hope.
