In the Hylfire mod you didnt have many skills from the start but you got a choice of skills when you level up. It is the same in Bonfire. But there is a quest giver on the first map, Skillix is his name, he sells skills like Heroism (attack and rage), Defense (Defense and Mana), Rage Control (rage), Meditation (mana), Wisdom (mana), Artifactor (mana etc), Onslaught (rage/ini).
That helps in case you don't get skills early on from the randomization. But sometimes we had to abandone even ok skills for the Gold you also can get instead in some situations on the Impossible Difficulty level...
The random skills given could be enhanced by a bigger chance for the low level skills early on, we will see if we get around to that...
