There's nothing worse in F2P games that work with gatcha systems than the feeling you get after spending all of your hard-earned premium currency on draws that net you nothing worth the time you spent on working towards that draw. I've played a LOT of F2P games, and while this game does a good job of giving you lots of premium currency if you complete all the dalies and hit all the milestones in Prize Fight, and also rewards you with gold cards for placing in the top percentages, the relic draw system I feel could use some changes. The Shard to Get relic as a means of rewarding you for spending your currency on character relics is a nice idea, but when that relic returns a silver character card you've already pulled numerous times, and that's after your 11x relic draws likely net you all silver and bronze cards, you tend to not see it as much of a reward anymore. You could argue that if they always gave gold cards that there would be a diminished value on gold cards in general, but when you think about the tedium involved in collecting all of the premium currency to make all those draws and get nothing good in return, the game itself becomes less competitive in terms of which games you want to spend your time playing as your time in this game becomes less important. This is especially true once you've completed all of the story fights, as there is now no way to get new character cards or relics outside of Prize Fight and gatcha draws. The gameplay is still fun, but as a mobile game where your characters run out of stamina after 2-3 fights, I only feel compelled to play in one or two short bursts a day, if even that, in favor of other more rewarding games.
