I don't think the problem is related to a role or role history. I was there as a barbarian, warlock, zenmaster, assassin, samurai and a paladin. Almost in all cases, I was a "pure role" after Reset Adventures. Sometimes, I got Giant Strike, sometimes Berserk, sometimes Tiger Strike but more often than I would like I got only +1 to Fortitude.
In the cases when I was able to get a trait, the idol changed its reward after game reloads. For example, I got +1 to Fortitude twice and then I got Giant Strike. In the "bad" cases, the idol insisted on +1 to Fortitude and even 20 game reloads weren't able to change its mind.
