In-depth gameplay means theres a lot to learn, the graphics are good and the balance is alright.
The downside to this game is it's too hard to obtain Legend rares, the gacha rate is 1%(my feeling is that its lower than 1%....), and Legends are so powerful and imbalanced esp. the red ones .
I regret not re-rollong more before I dove into this game. Now I cant really start over since I already spent money on cardback and avatar.
