Have played two games under Pitched battle system. I like the points being back in and the balancing though only two games in so wont make a firm decision until I get a few games under my wing. Both games were against Sylvaneth though. First game was Escalation which was a fun and challenging scenario. We both finished on same objective points and I won a marginal victory on model lost count back.
Second game I was tabled by the Sylvaneth. He had slightly different list and mine was a list with a cavalry focus this time. The empire knights were woeful. Don't find them effective at all in this game. Their stats are poor (cant understand how a lance doesn't do rend). Had four units (5 knights each unit) charge into unit of kurnoth with three models and over two turns of combat all I did was one wound. Kurnoth have ability to raise a thicket and re roll any failed saves. So the dice economy is as follows, 4+ to hit, 4+ to wound then he has 4+ to save and re-roll failed saves. So those dice are whittled down to nothing. As I said, one wound only.
Wont be playing knights for a long time. Over costed for what they can do. They feel more like a skirmish cavalry than what traditionally knights should be like.
