But Mirage-sensei it also depends what kind of team you have and if you need AoE Def down or not and how fast you can burst with your team :O
My wind team is slow and can only cover AoE-B-Frame def down. Therefore I would go with Hercules.
A dark team with Satan AW, Pluto, Osiris and Chernobog will probably run with Shingen because of snipper as ex.
You can also use Dark Ama/Samael later instead of Osiris/Satan AW and run with Hercules+PF
yea and Hercules with Relic weapon burst fast enough, so that you can get your def down even if you only cover -20%def down.
You won't need BP that much later, if you get stronger.
