Right now its looking to me that defensive Axis builds are favored, especially with the current ruling on Damage Resilient applying to all attacks and the presence of Range U units with Advanced Reactive Fire. Not sure how great the Allied mobility is when you're running into a meatgrinder/wall.
On the advance I think that the Axis are still favored due to not only the hardiness of their units, but the prevalence of the Assault ability on their heroes which, albeit briefly, counteracts the relatively low speed of the Axis infantry.
I'm thinking that maybe the Allied heavy walkers with their transport ability will help with the advance (and I imagine they'll block LOS per normal for vehicles, so you could march up quite a few units behind them), but I'm still not sure about how to handle entrenched Axis infantry with the Damage Resilient Ability. Ignoring cover isn't a problem at Range 3 or closer (Phasers, UGLs, Flame Weapons), but then you still need to deal with Damage Resilient, no matter what you're attacking with.
Thoughts?
