What happens in v2?
Lots of things from what I heard from people who play JPCC.
UR Rate goes from 1.7% to 7%. They added missions which allows people to get prysma regularly. 2000 arcana coins will always pull a rare arcana. Dungeons with enhancer reward to level up. Special UR rotation in taverns during which certain UR has an even higher chance of being pulled.
edit: people also complain of having too many rings and in fact rings are used to buy stamina fruit lol
