Why wasn't Derby evading?
I deliberately used the non-evade boss style for Derby for the reason being that watching Derby use the evade version would not be too interesting to watch. If Derby had his evade style then he would use his evading maneuvers far too often and use his normal attacks less regularly. I did some practice fights beforehand with Hal and Derby with his evade style and I can tell you that these fights were far too repetitive. It went like this -
1-Derby would strafe around Hal without attacking.
2-Hal attacks. Derby blocks, then performs uppercut.
3-Hal blocks, repeat from 1.

I'll try and use the evade style for the next fight though. I can't make any promises that it will work out perfectly. I'll be tweaking Derby's stats to try and get a better result.
