If half of what I'm hearing is true, then I can only say...

GOOD!

I know that scissor/paper/rock is a nice principle, but spearmen were VASTLY overpowered in MTW compared to their real-life counterparts, and when hit at the flank or rear, they should indeed rout almost instantly. That's why generals spent so much time trying to secure their own flanks while trying to flank their opponents.

It's what happened in real life, time and time again. Doesn't mean that cavalry can't be countered, but hearing this is a heartening note of realism across my humble desktop...
