Don't get me wrong, I love the gameplay, the character design, story and honestly everything about it. Except the monetization, hear me out. It's not "Woe is me, this is another gotcha game" its more that the prizes on the store don't scream impulse buy, it screams give me your wallet. for example, Almost two pulls for 30 dollars is a bit much, the store has many such items on sale. I understand the effort put into the game itself but im sorry the pulls are not worth that, under no circumstances

A very good game. It's been fun but has started to move into repetitive and tedious state. Chaos dungeons are taking too long to do daily so I mainly log in, do a few menial tasks then log out. Character designs are getting a bit too gooner for me and the weird lack of variety (no guys or animal/cyborg designs now for some reason) is adding to the boredom.

Drop rates are terrible, the shared pool between Partners and Combatants make pulling the real Nightmare of this game. Not even pity rate guarantees a 5 star banner item. The progression continues to be slow, with no combat speed increase nor automatic play in some modes. You may find fun in combining, refining decks, but it seems the effort to do so is immense.
