The moment that soured me on Try was the aquatic mobile suit team and how it was just a joke, despite them getting at least a little buildup.
I feel like if that same idea were used in Build Fighters they would have given the aquatic suits a good showing, even if they were in a similar disadvantageous scenario. The whole idea of bringing in aquatic specialists to begin with is that it can make for an interesting combat scenario that goes into a non-traditional environment. The reason being that Build Fighters was made with reverence towards Gundam's history and wouldn't have an extended buildup to a joke about how "these parts of Gundam are dumb, these Mobile Suits suck."
And it's not just the aquatic MS, it basically feels like Try is just shitting on everything except the characters and concepts it thinks are the best. "People think Minato is cool? Oh, better toss aside the parts that made people like him and make him a creep who hotglues MS girls, because we don't want people to like Minato."
