I just hit Floor 88, yeah don't bother wasting Magatama/Stamina on this. I have a full 6* (5* Awakened) team and the enemies have a lot of health and hit hard, not to mention their abilities (healing, shields, AOE attacks, silence, etc.).

I have:

Oda (30% ATK to all) - Leader
Hideyoshi
Imagawa
Ieyasu

All, as mentioned are fully leveled and 6*, as well as fully stat-capped. This is ridiculous. I can't imagine how people with non-gatcha characters are fairing...

What a waste so far, and you'd still need to farm the higher runs for a chance at drops to awaken the 5*. Good luck doing that with a luck leader and not damage, as the enemies would pose even more of a problem.

I don't think this game is for me. I have 450+ saved Magatama and I don't even care. So much grinding, difficult events (that definitely won't be doable unless you have the latest/greatest from the PAID gatcha), and I just don't see the point anymore. I'll probably finish off the 100k points, since I've come this far, but if the next event is the same, I'll probably just drop this game entirely.
