Prices are insultingly high; I'd pay if I got more for the money. There are a few quality of life improvements that should be made, such as showing in the selection screen which elements you're already refining and not registering time spent. It seems they're no longer developing it. Game grinds to a halt at level 30 with the latest patch. Gets boring. Some of the rank goals are just absurd. Get x to level 150 (impossible). I feel like the devs don't even play this. Now they removed free relics.
