One thing to keep in mind is the fact that we are used to vanilla Axis, which are blatantly overpowered. If you use vanilla Axis as a reference point, you will be disappointed in the sense that BM Axis have been nerfed in comparison and can’t pull off such easy wins anymore. It will take more effort to win as Axis now, but is it easier to win with Allies? I’m not convinced. I’ve lost as Allies in BM while I’ve never lost as Axis.
Also, it’s impossible to balance a game for all levels of play. For example, some tabletop players think vanilla Allies nearly always win and are overpowered, so they bid for Axis. The bid varies a lot between tiers, with the bid getting higher as the tier goes up, which means that different players interpret the balance differently. There will inevitably be at least a part of the spectrum of players that will require a balancing mechanic, whether it’s a bid or taking off NOs.
With that being said, I’ve been thinking about a couple of NOs since BM2 to address some issues I’ve found while playing, and they would slightly help the Axis.
