The upgrades cost too much and I am not sure they are working right....the upgrade cost 15 tier 1 element.....not good after farming four 4 hours of game time
The percentages are definitely off. I failed an 80% five times in a row. I realize that's statistically possible, but I don't believe the percentages are accurate, which makes me feel like it's a ploy to make me buy/spend crystals. I realize you guys have to monetize, but please don't rely on gimmicks.
