Welp, here's my idea. Made in paint over a 6 hour period or so. I May or may not edit this.
Warfare Rules:
So here's the basics:
I call this mode 'Warfare', and its designed to try and keep 'mobbing' from occurring (where all the players are in one area fighting as a mob) by having a large wall that you can't cross without a flying Ult or teleportation (Think Athena, Thanatos, Apollo, Thor, the teleport to gods Item, ect). You could almost consider this two large siege maps stuck together, with an expanded jungle, with the gold fury and fire giant in the center, accessible only through portals. These portals can be captured by defeating the Sand Giants (from domination maps). Capturing these is purely optional however and you can completely ignore them, as the lanes will be running past the turret, without entering its range.
The green and purple portals can be used by anyone, and are always open, to provide a bit more maneuverability in the jungle.
