I feel like ZZrots kind of missed the mark.

ZZrot's portal is a pretty cool idea and I like it, but I'm a little disappointed. The item that was made for pushing towers is really useful for freezing minion waves and very weak at pushing towers unless you have fast wave clearing and can tank a few tower shots here and there .

Here's how it's working, you place the portal, the voidlings run out and attack the enemy minions, die, then a new one spawns and attacks the exact same minion wave, dies, and the cycle continues over and over until the enemy team closes in on the portal and kills it like it's nothing.

I'm finding that it isn't really worth getting. Any ideas on how it should be used, or should be changed?
