So my question is really for the sake of all the campaigns (and general balance) would it be ok to vary up what I buy, or do I need to buy each factions mirrors? Like if I buy Command Squad for the Allies, do I need to buy the Command squad for the Axis? Same with the special ops, the walkers, etc.?
What I've been doing is kind of building them differently: The Allies have Recon and Command Squads and more Light Walkers, whereas the Axis have the Special Ops and more Heavy Walkers, and I plan to make the SSU mostly air and some walkers, but with several vanilla infiltry units backed by the various commisars. Should this work out for balance as long as everything is balanced point wise or are there things every faction needs?
