5v5 on Prison with tough grunts - Actually really fun!

Just wondering if anyone out there finds 5v5 games on Prison to be more fun than the suggested player limit or the larger maps. Tried it out a couple of times with AIs and they turn out well.

It's not perfect, changing grunt and towers to "strong" in the game options helps keep the demigod/NPC balance and increasing the death penalty helps offset what sometimes feels like zerg respawning demis if you try to push the citidel, but I still think I find that kind of match more fun than the default options.

Anyone else out there tried those game options? It might be a hint towards what to do with future maps if the general concensus is that it's better.
