Asymmetric E-sports Thread

My friend came up with an interesting game idea a few days ago.

His idea was a game in which one player would play against five in a competitive match. The one player would be playing an RTS/god game style game, controlling the terrain, dozens of units, etc. while the five players would be playing single units in a team, much like LoL or DOTA.

I think it's a great idea, and while I'm not crazy interested in developing an e-sport type game, this gets my creative juices going.

Are there any games that do something like this?
Could you see this being a viable e-sport or just a interesting multiplayer concept? I'm no expert on e-sports, although I've played LoL quite a bit in my day.
At the very least, I think asymmetric multiplayer play is pretty damn interesting and is a growing trend in games (like Evolve, or maybe Titanfall).

You could make a Warcraft3 or Starcraft2 mod that implements this type of gameplay relatively fast.
I think the concept is OK, but it needs to be really balanced to work.

I don't think it would work. The idea of capturing multiple audiences sounds nice but it removes the competitive nature of the matches, since players don't compete, gauge their skills, directly against each other in a mach, but to their peers in a statistics ladder. Insert Venn diagram here. Instead of two audiences you can reliably capture the overlap, which isn't big enough and will bleed out.

Another problem with this is that it has to be balanced throughout and between multiple skillsets, meaning you will end up with a lower pool of content, more Demigod than Dota2.

It can be competitive, as can whistling dixie, but it won't be 'legitimate sport' competitive.
