What are your thoughts on a "Swarm Host"-styled ability?
Azir's "minion-mancer" style is really cool, but one thing I've always wanted to see in League is a Champion who emphasizes "Zerging" an enemy. As in, spawning dozens (if not hundreds) of little ankle-biters that will overrun an enemy position if their breeder is not killed. That would be really cool, IMO.
In relation to that, I have a prototype for an ultimate ability that said "Zerging" Champion could use. Keep in mind, this is just a quick brainstorming. Take it with a grain of salt.
Infestation
(Toggle) Mark a target location. Every second, you spawn 1/2/3 Broodlings that will attack toward your marked location. These Broodlings cannot be targeted, but attack at melee range, do not cause unit collision, cannot attack structures, and expire after 3-5 seconds. Costs mana every second while toggled on; upkeep cost increases every second. Broodlings perish if you are killed.
Think of this like a Starcraft 2 Swarm Host on steroids. You can walk around with this on, constantly popping out minions that will overrun your enemies if they don't kill you quickly.
Any thoughts?
