Jinx and runaans hurricane
I have looked at this and played this build on the champ many times, and have had some in game feedback but would like to layout the functionality and hear your thoughts
So jinx's rocket effect is splash damage at 110% her ad on basic attack, and with runnans hurricane it adds extra projectiles that can proc this splash damage. The actual projectile does partial damage, but the aoe splash is not changed, it does 110% ad damage. This means you can effectively hit the whole team with one hit, and potentially one person with 330% your ad on one basic attack if in all splash ranges.
instead, gaining even MORE damage and almost as much attack speed for not much more money.
