You would think. What hurts Allies is if they can’t land on beaches more than once and for axis killing planes with art.
Most say game favors axis.
I’ve been testing using a d8 die and so far
Allies 4 to 1. Every allies win game down to getting 3rd city on t9. Only thing I have come across is axis art against planes. May increase number. By going to d8 or chance of rolling a 6 decrease with a d8 instead of a d6. This helps allies with less chance of landings on beaches. Plus an but increase in deployment but that goes both ways
