because that would be pretty bad
once tf can 1v1 olaf, and champions can 1v1, why is it still a team game?
are you saying orianna should be able to 1v1 xin zhao? then what of her team abilities? obvious op for utility champs
same example, how about her aoe? so she can 1v1 xin with aoe. xin has to be able to 1v1 her without significant aoe. So what does that speak of balance?
and power curves. When can orianna 1v1 xin on equal terms? (she should really never be able to, considering xin is heavily focused on dueling, while orianna is not)
