Why is this game so poorly designed?

So I get that they want to make you waste crystals on refreshing the events for these capital ships. But why make them so that you have to learn how to use a fleet in a sub-optimal way? It just feels so backwards to me. Like, they already mess with the stats for the enemy ships. Why not design the event so that it doesn't take such a long long time to get a single run in? They've already built in a million other frustration mechanics just getting to that point. Why add more? It already takes forever to farm up everyone for the events, and then it takes the ideal line ups and dismantled them. No one is using imperial ships with executor. And anyone that is, is a fool. At least put a sim option on all these capital ships things.
