So, it seems that many comments I've viewed online have mainly bad things to say about basic human knights. Around here and elsewhere, it seems that Brettonians aren't viewed as a high-tier list, and they're supposed to be the best cavalry army (flying V and all that).
I admit that generic ones (S3 T3 for ~20-24pts) are not so hot, but otherwise I'm not quite sure exactly what's so bad about them. Ranks, attacks, Ld...?
So my question: Do you think human knights/heavy cavalry are crappy? If so, how would you improve them (least possible change) to make them worthwhile?
