This is a cross post from my post in reddit.
The Fairy System feels very outdated. It is very p2w to get the perfect fairy and I refuse to spend more.
Here are some suggestions to make it better:
Enable us to level up another fairy without releasing our current fairy first.
Introduce a fail stack system (Like horse skill change coupon)
Convert radiant fairy to reroll orbs.
The fairies are serving their purpose of being a forced convenience item to push players to give the loot goblins at PA money. I highly doubt they will touch this system because its making them money.
