I think you misunderstand the game mechanics of MoM. giving +1 atk to a squad of pikemen didn't give you +8 atk. It gave each figure +1 atk true. Each figure in a stack rolled to hit, and had a 30% chance to hit. modified by + hit modifiers, or - hit modifiers. Then as I recall, it's attack strength (swords) were rolled off vs the defenders strength (shields). It was not an attack made at the sum total of the attack of each individual figure, it was one attack per figure at it's attack. This was important, because if you had drasticly more swords than your opponent had shields, you clobbered him. The forumla is all in the manual, but I know it was not as simple as adding the entire attack strength for all the figures together and attacking.
Everything the developers of this game have lead us to believe, imply to me that when you produce a pikeman you will get one pikeman. Not 8. What you are arguing for is pretty much exactly the same thing as a tactics skill. you should be able to field 8 pikeman, or one great wyrm. I think there is some dissagreement about just how many pikemen vs how many great wyrms, but that's really something for the beta to figure out. So really, you are arguing for the same concept. but you want them clumped into little exactly the same sized boxes like MoM? In Master of magic you were limmited by "square foot" of troops for lack of a better term
you could field 8 pikemen, because they took up the same ammount of space as one great wyrm 
I like the idea of this system better, you have a squad of 8 (for continuity's sake) pikemen, one of which you want to give a +3 pike you made to, and leather armor of bravery or w/e and make him the leader of the squad. The rest are just cookie cutter pikemen.
I don't think the entire system will be reactionary. I think some of it will. Being hard coded into your strat in master of magic once you'd made your picks with really no room for variation could have been brutal if the AI was smarter. I think there will be plenty of choices to make initially, and plenty to make as the game goes on.
You'll make choices about which tech tree you like, which general spell set you like the idea of having (like you did in MoM) without geting specific spells (by chosing your faction), and the rest will be determined by what research you get (like in MoM), and what shards you get to amplify your spells or maybe some of the more powerful ones will require you to go get specific shards (not like MoM). This sounds to me like it could be modded to master of magic with the drop of a hat, but sounds more fun this way!
(and I don't know about you, but my pikemen never did manage to fend off calvary to any measure of effect. )
Again, master of magic used it's own form of logistics, it was just rather basic, because of the limitations of the tactial engine. The tactical engine is not going to be turn based as it was in MoM, and you are not going to have neat little squares of troops to move "one square" at a time across a tactical map, at least that's what I gather given the screenshots we've seen.
