The actual threats antagonists pose or just more dangerous villains in general, using the garleans as an example I feel like stormblood has just shown them as completely incompetent and quite easy to route. We've heard time and time again how they are this big looming threat and yet every time we encounter them it's made out to be rather mundane and of no real impact or consequence. I mean I guess it comes down to funding but any of the 'battles' we see in cutscenes just look plain pathetic, Doma especially. Zenos on his own was great but everyone else and the empire as a fighting force just came off as lackluster and I think any cutscenes we get that display large conflicts in future should have just a little more work put into them.
Speaking of warfare within this universe hearing general strategies for the average fighting man would be interesting, like I remember hearing Raubahn mentioning how scary it is to take on magitek armor for the first time, I'd like to hear more specifics about how standard rank and file actually deal with forces tougher than them, same with ishgard and the dragons as well or the general application of mages and how non-magic infantry deal with them, Oh and airships as well. How do Alliance forces take out juggernauts or dreadnoughts?
