You are seriously comparing the squad wipe chance from a mortar with the b4? Also soft counter, you guys are so funny. It is not that you can just drive down the street to the enemy base to kill it with grenades.
Yup. Every time I've played axis since the new patch, mortars have done far more damage to me than any B4, and they hit the field very early too.
I agree that soft counters aren't ideal, but you'll have to ask Relic why they have promoted having some hard counters being doctrinal only, when there is a possibility that the opposing player either A) doesn't have the commander at all, or B) they haven't got that commander in their loadout. This is not a problem suffered only by those who face B4 though. It's ever present on numerous other units, on both factions.
Coh 1 gave you the choice of 3 doctrines. If you selected a doctrine early and paid the price later, that was your own mistake. You can't say the same for coh 2.
