@Gamerman01:
Merely comparing the stats of move 2, cost 6, attack 3 and defend 3 with other units is to ignore an awful lot of considerations.
Yeah alot of the advantages of tanks are ‘intangible’ and difficult to summarize adequately. It’s not just the punch they bring that make them effective, but the fact that the enemy will need to react to them (eg tighten up defensive lines, abandon positions that can be taken by blitzing, combine all forces into one big army in order to prevent being divided and conquered). A mass of art and inf and mech is less likely to be mobile enough to trap retreating armies or pull of feats of dividing and conquering.
As far as the argument that you don’t need tanks because you can buy tacs and figs to come behind the mech……well there is a certain logic to that, but I don’t think it encompasses every consideration… IMO if you want to go for Moscow on G5-G7 then the most efficient purchasing strategy will include some tanks on G2/G3 (and maybe G4). In that scenario, there isn’t time to buy enough art to get max offensive power from the mech. It’s hard to base a strategy on fighter and bomber buys on G3/G4/G5/G6 when I should adjust my purchases to what the Allies are doing in the Atlantic and Africa.
