lee sin R, make R a dynamic ability
based on which ability he used last before his R.
just as some examples.
Q for more pushing power/better knockup.
W for a bigger self shield
E for more damage.
just something to get him out of the wardhop R QQ combo.
so in short it would make him weaker with just his base ultimate, but in turn he would pick up some more utility.
). We don't need another.
