Couldn't beat Olgierd von Everec...

[Knavery]

So, I just got through the main game, which was really enjoyable. I just started the Blood and Stone expansion. The decisions I made forced me to fight Olgierd. To make a long story short, I couldn't beat him--even on easy. And I'm level 35, with superior feline everything. This should have been an easy fight. Needless to say, I reloaded my last save and avoided the fight.

Should I be using a controller to make this easier? In vanilla, the keyboard was fine, but it seems much deeper strats are needed in the expansion. I feel guilty for not spending more time trying, but it was so one-sided I figured what's the point?
