Easy. Increase the rates because fuck this Genshin 5 star bs. Allow dupe tokens for the high rarity ones to be obtained from say weekly or monthly quests. Give a daily free roll (idk if they've already done this). Make the bonus buffs less. Make the pets not affect pvp - why would they even let that thing join pvp?

Best suggestion? REMOVE IT. VESPA. FOR THE LOVE OF GOD. THIS WEIRD SYSTEM BREAKS THE LORE AND IMMERSION OF THE GAME TERRIBLY. THEY'RE UGLY, AND MASSIVELY INSULT THE BEAUTY OF THE ACTUAL BOSSES.

Vespa needs to stop releasing a new upgrade system every blue moon. The grind in the game is already tiring enough - I quit because of how trashy it became. I dont feel like in 2020 a game should demand you to leave it on repeat all day and all night. Only exception is Another Eden cause I can not play for months straight and I'll miss nothing.

Vespa needs to look at the success of other gacha games and analyse their upgrade systems just to see how ridiculous theirs is. Arknights is amazing, it doesnt demand much grind time and sanity is slow recharging, but because the upgrade system isnt so ridiculous, I can consistently build new toys to the max without feeling burnout, which I get from kings raid after not even a single week of coming back. The kings raid gameplay loop is so boring, I think only casuals who arent tied up in pvp can enjoy it.
