I've found your channel because of your solos, and usually that's more of my cup of tea. I often dont find TAs interesting, but I always watch them anyway because I'm an fgo nerd. However, everytime a TA has more than 3 turns and becomes more of a puzzle building, then it turns out to something I can't help but to appreciate. Even class disadvantage comes to play while building these setups. Amazing runs.
Yeah usually shorter TAs feel more strict in the way that you more or less need to follow the predetermined strategy you have formed before even beginning the battle, but in this CQ you can adapt to what happens and change strategy on the go.
For Ishtar I find it though since she had somewhat of an AU already. For Eresh, even though her animation are already really cool imo, I wouldn't mind a small AU to update her sprite or modernize a bit her animations.
