I chose Fighter. Much improved over previous playtests. Barbarian just.... ARG! Weaker in each succeeding playtest, and now much less versatile, too (no Dex-based Barbarian options). I can see liking it if you want to be Strong do lots of damage with strength and get hit all the time, but now much less versatile. I also don't much care for the totem path getting "spells". Barbarians aren't rangers or druids.
In previous playtests my "Barbarian" was re-skinned as a "Ninja" who used all the dex-based stuff (Hawk Totem) and the "rage" was actually a "combat trance". She could use Dex to hit (she just didn't get the damage bonus because it wasn't STR based). Now she's just not going to use a lot of the abilities (she isn't reckless, and her main weapons are dex-based, so no reason to use reckless attack). She'll still "rage" but now it is just damage reduction (she blocks attacks with her arm).
I hope that the Dex-barian comes back in a future book, in the meantime I'll just be less effective at fighting I guess and also refuse to use the "spells" that the animal totem stuff gives (it's not her style).
