...They did that in CoH 1. It was insanely complex...
All I'm saying is that balancing one unit to be properly balanced against 2-3 other factions units is a tall bloody order. The lack of fine tuning from CoH2's health+recieved acc system necessitated years and years of trial and error to get it to an acceptable level.
I don't think that target tables + infantry types are a bad idea. I think that players just need to have a way to see it in game. Again, like the unit encyclopedia of Men of War.
Or even Lambda Wars, where each infantry unit is Light, Medium, or Heavy. Each unit type is affected more by different weapon types, consistently.
And also in Lambda Wars, the unit description at the bottom of the screen lists the infantry type and its weapon, and when you mouse over this, it tells you the modifiers against other infantry types.
