No advancement, unless you spend
So I initially loved the game. Still do. But, you can’t even gain any SSR and forget UR without spending so much money on a rip-off game. I loved playing it because the characters. But you’re stuck unless you choose to spend. I stuck it out for awhile to see if they have even have pity drops. Nope you’re stuck with lame SR that barely dent opposition. For a rip-off game trying to cash out before copyrights are reported.
