Mr Internet, your proposed changes sound good

I agree, but in this forum, we're talking about medieval 2 game not Rome total war.
I know, that the hastati/legionaire was just an example, but medieval combat was a lot different.
Light infantry got mixed in quick with enemy light infantry (the BraveHeart movie showed it pretty good), into a giant mass killing field and everyone was fighting. Light infantry as well as probably heavy infantry was less likely to hold any formation after they were set loose and the only tight formation of I could think of were the pole-men, filling in the role of protection against cavalr charges.

I think M2TW still faced many problems, that RTW was plagued with, since it was pretty much the same engine with a bit of updating. I think, the most rants I have seen posted were about either the charging and the fighting, which were reported early on, by members, after the release.

Hopefully other companies jump on the bandwagon after the success of M2TW and RTW sale-wise. It never hurts to have a competition instead of one Monopolizing on the idea.
