If Master Yi was a 2015 champion
Passive would deal 100% damage and provide twice bonus Attack Speed from items. Q and E would be one ability and have addidional Ekko-like dash. Meditae would have twice less cooldown and scale off from AD. E would be secondary dash or aoe projectile. Highlander cleanse all CC and enpower Alpha Strike to have no cooldown.
And above all.. HE WOULD BE LCS VIABLE PICk.
are not completely toxic to play against
