why buy armor?

(ie, Mech Infantry can hold its own against twice their number of leg infantry in general, but tend to cost about 3x the price). IMO, you are paying too much for simply mobility. YMMV.

First, you're making the same mistake again by making a comparison of just 2 elements (mech and leg infantry). Foot infantry will for example have a very hard time preventing you taking out an artillery park further back. And armor can suddenly find missiles flying from a direction they thought safe.
Also, mech infantry can take on much more than twice their number. Just not all at the same time. Which is the whole point of why you play on too small a map. You can't concentrate on just part of the force.
