The most enjoyable build/patch of your favourite champion. Personally mine was 2014 Kha’zix. His ulti is the same now except it gave 50% damage reduction, his pre evolve w slows and his q did % base damage rather than cooldown reduction. He could kill squishies and tanks while also being unkillable due to stealth/ evolve e 2nd/ dmg reduction. 2018 Kha’zix was also fun where evolved r gave you passive stealth + MS in bushes at all times. What’s everyone else’s?
