When it comes to skills, infantry, and especially armor, get the very best there is to offer such as breaths, special spiral, and in armors case, fighter skills. This leaves cavalry and fliers without any unique combat skills for themselves. Being considered the stronger move type for a while before armors really stepped up, it's understandable why IS would want to leave them out of the fun. Fliers on the other hand don't seem to make much sense, as I'm not sure their strengths are cause enough to keep them from accessing strong, unique skills. Perhaps down they line they will decide to give them some love (Edit: Other than more movement based skills). Do you think this is unwarranted, or do you agree with the decision?
