Dont know, but with so many commander options I think it adds to the variety of styles of gameplay. In vCoH: 2 factions per side x 3 doctrines each. If you wanted to go defensive with Germans you chose either Wehr Defensive doctrine or PE Luftwaffe (because of the static weapons) and to a lesser degree scorched earth because of the barricades, booby traps. In Coh2 you can go def with Festung armor (static PaK43, hull down, Command Panzer with def buffs), Fortified armor (Elefant instead of PaK43), the new Defensive doctrine and maybe Joint operations and Osttruppen doctrine (because of the trenches). And here we have about 3-4 different styles of just defensive play and the game isn't even fully developed yet.
Yes I agree the doctrines in vCoh were more concentrated (as in AT, Defense, Luftwaffe…) since they were fewer and in Coh2 we have some same units and abilities that are in different Commanders. Although both games have similar gameplay I can't say which one is better and that's because of the different doctrine options – a different way of playing. I'm not saying the new system is better or worse, it's just different. And so far I like it. Maybe people are just too used to doctrines in vCoh. Anways we cannot fully compare it to vCoh until all the content is fully released. Just my thoughts…
