One unique aspect of this change is that getting expansions and making chapter progress decreases your sustainable tournament ability. That's different this time.
But doesn't the increase in tournament and Spire squad sizes get outweighed by the increase in training speed and training size that comes from leveling up the military buildings and the AWs that do the same? If someone does not keep their buildings leveled up, so that their increase in troop production does not keep up with increased squad sizes, that is not your fault or my fault or Inno's fault. That is the choice of that player to fall behind.
When you look at things like that, it definitely feels that fighters have much more control over their numbers than caterers do, so fighting is not nearly as broken as catering is in the new format.
