Comparatively, yes, I would say so. I have managed to get by with the thief class although I couldn't consistently beat the orc (I may have squeezed one win out after boosting strength if memory serves).
I can't speak in detail about the other classes rn, as I can only remember doing submissive, pacifist play throughs with them. But I think Majalis said he planned on rebalancing combat soon, especially fixing the way mounting currently works. Glad I could help you
