4.0
What I love: great gameplay, nostalgic arts, funny stories, great characters, many challenges, the developers are quite generous, they fix bugs quickly
What I don't love: enemies are soooo strong, ridiculous level of difficulty (at least for F2P), too much time (and brain neurons=)) needed, large update file size (2GB for every major update o.O)
I'm not sure about SSR rate anymore, sometimes I got SSR after 20-40 summons, sometimes I have to hit pity summon (100 vouchers). Ironically, my SSRs units are mostly cute girls while I want to collect husbandos
Seriously, is my account labeled as "male commander"?
It's a very slow-paced game, so you have to be really patience or pay a lot to speed up progress. But at least, it's a true gem among so many mobiles games these days.
