Zz'Rot Portal [Oh god, Why]
Riot, no. No please. No. NO. NOOOOO.
What happens when tanks with already fast clear times stack it particularly when they have intrinsic abilities to buff their defenses? Garen, Malphite, and Trundle being the obvious examples; or hell, Trundle stealing someone's armor and mr for the massive amount and then spitting out two super voidspawn that then smash a turret instantly.
THIS IS TERRIBLE, ESPECIALLY WHEN COUPLED WITH DECREASED ITEM COOLDOWN
WITH ZZ'ROT PORTAL, ANYONE?! HOPE YOU LIKE THE TURRET SMASHING TRAIN
Edit: Poking around the forum reveals people using it in groups OH BOY 5 PORTALS MID. Fix this so that voidspawn have a 5-3 sec ticker before explosion (which can't hurt champions), no ability to attack beyond the detonation, and have health that decays over time.
