Actually, It is the balanced issue, but I can't find category, so I suggest this forum...
Guan Yu is the greatest champion in this game, while Son Ren is just a female Vanguard.
But if they are duelling, not having any support by other characters, Son Ren defeat Guan Yu very easily.
I think champion class character should be stronger and vanguard class character should be weaker when dueling, because vanguard specialize slaughtering soldiers, not duelling.
If you have time gaming, duel Guan Yu and Son Ren. You'll figure out what I mean.
Thank to reading my opinion, take care yourself to COVID.
Have a good weekend
