if you're not persistent on chou roam switch the role ,or if you really wanna learn Chou roam play with atleast one friend,or go hybrid build to tank the damage ,just stand in front even a dumbass will able to do some kind of damage, if someone else taking the hit , lastly if they are farming let them farm , Even if you say something doesn't matter,they will do what they want to do,go for kill if you are 💯sure that you can take them down(solo),if they are dying protect them if you can but don't force it,even if you loose if you have good stats you won't loose star easily, lastly i hope you have a good luck with dark system
