Suggestion for Zz'Rot Portal

What if Zz'Rot minions also gained the Point Runner passive and every 4th one gained a shield like a Siege Minion that made it take reduced damage versus towers (like 70% reduced damage since it has so few health). I feel like this would give the item a slight nudge in the right direction since it is no longer a super popular pick, even among split pushers. It's mainly used by cult fanatics who really like the item for how cool and unique it is.
