I feel like the AI used to make a big long battle line, keep its cavalry on the flanks and commit them after engagement in TTW1.
But now I often find in TWW2 I seem to find the AI approaching me in a column committing its units piecemeal to a big centre blob.
It seems like quite a downgrade and I don't like it.
From videos I made of TWW2:
Like a marching column, extremely poor formation
And from videos I made of TWW1
This is probably also the cause of why the AI clumps onto lords and monsters so badly now. This happens constantly and is a seriously less fun experience than TWW1.
