An idea for future development would be to have it so we could compete with each other like the challenge levels. Just pick the starting territory and the map and the computer takes over with auto attack and auto upgrade.

Maybe have a little AP reward per win, and a matching system similar to regular Warzone (that way juggernauts aren’t wrecking new guys).

I could see something like this happening. As for the AP rewards, I think it would be more interesting if it was an AP wager, similar to coin games, where both players wager some of their current banked AP, let's say 10 each, and the winner takes the total wager, the winner takes 20. There shouldn't an "AP tax" however, unlike the coin games. If 20 AP is up for grabs, 20 AP should be awarded.

And the 4s actions + Attacks in, and this is what we now have with WZIB, no?

These would be no interaction

This is a terrible idea. If you want to wager, stick with coins. Betting AP just means some poor souls are going to lose their hard earned AP.
