Problem with Howies is they're T3, expensive, no armor protection and you can't camp it near a ambulance for it's healing, because OKW will have a Stuka for counter arty that'll just squad wipe the howie's in one shot.
I'm not in favor of blobbing at all. Just saying OKW can do it with out worrying about it for most of the game. ISG come out way early compared to the Howie and OKW doesn't have to manage it's units nearly as much. ISG, insta-pin, take OKW blob and mop up USF.
I'll argue that Axis doesn't have to micro near as much as USF. OKW sturm pios early game? Come on, that' nearly a click and forget unit in early game.
USF is realy hard to micro, I hear you. It's the most micro intensive faction may I say, but they are the exception. For some strange reason, Relic made USF very hard to play if you realy are the "combined arms" type. Buuuut.... if you are not, things change. Build your blobus santctus with bars and zookas together with an AT gun or two and see if anyone can realy touch you.
