since the devs have confirmed they will be buffing old charecters, i have some simple ideas on what changes i would like to see in certain charecters, feel free to opine on any of them

Kafka - she can cause any DOT present on the enemy to crit with a fixed chance of 30/150 CRIT ratio

Black swan - instead of 20% def shred, gives 40% def shred from her E skill and her base atk stacks more arcana

Silver wolf - instead of random elements, she can now specifically implant the weakness element of the first character on the team

jingliu - I think her base kit is fine, she just needs a multipliers increase for her enhanced E skill and ultimate to be on par with newer DPS

dr. ratio - same as jingliu I think he really just needs a multipliers increase enough to kill smaller mobs with one use of his E skill (counting the follow up) I think his base kit is fine, although a 3rd trigger for his ultimate in his base kit would be helpful

blade and seelie - I have absolutely no idea 💀🙏
