Gacha rate is bad, only 0.7% chance to get featured student. Farming materials on last stage of Bounty still gives lowest tier materials. The game has PVP and Raid rankings but the game wont let you have the meta students available due to low gacha rate and they are limited characters. Trying to compensate it with levelling up non gacha students isnt gonna make a difference because the game has worst drop rate on higher tier materials. Also, limited students are way too overpowered.
