Suggestion about YI's Alpha Strike
What Alpha Strike is right now Active: Master Yi blinks to the target enemy, dealing physical damage to it and up to 3 nearby enemies, to then reappear next to his main target. Non-champions receive increased damage. Master Yi becomes untargetable over Alpha Strike's duration, and can Critical strike, dealing 60% bonus physical damage to all enemies. Basic attacks reduce Alpha Strike's cooldown by 1 second.
In addition to that Every damaged enemy is Marked for 3 seconds Master Yi can recast the ability for free to teleport and strike a marked target consuming all marks dealing physical damage equals 5% of target's max health + 15% of its missing health
The idea to the ADDITION part is to increase Yi's Mobility allowing him and his opponents to play around something
