Zz'Rot Portal is still pretty bad at siege

I just tried out the new Zz'Rot Portal in a custom game.

The voidspawns are too squishy to tank minions, or a tower shot. The range is too short to take multiple towers reliably, unless the portal is positioned in between the towers. The exception is the mid tower, where if you put the portal right outside of the turret range, it will just barely travel to the second tower.

At the same time, I can feel the extra damage. It's now rewarding when used carefully, not just whenever you plop it down somewhere.

Now that said, I think the voidspawn hp nerf was too strong. It can be killed by AoE spells too easily, so it can't be used to siege when there are enemies under tower. It's only really useful if you're trying to take a tower by yourself as a frontline. I can see Yorick being good with this, and I can see how this could be a strong splitpush tool to complement a splitpusher. But I don't see this becoming a good siege item.

If Riot really wants to make this a siege tool, please make the Voidspawn's hp scale off of all nearby allies' hp. This would still make it weak for stalling a lane and roaming (since it would have very little hp), okay for splitpushing with it, but amazing when sieging with it.
