And three-sided war isn't working for AH.
We are marching the same path WBs did, just a few years later and with three sides instead of two. Identical path.
At least AH has effectively defeated its equivalent competiton so it has that going for it.
Hmm. Three sided war isn't working, marching the same path as WBs did but 3 sides instead of two, so it's not working but defeated it's competition.....
So, it's working?
Two sided war always has the ability to have one side dominate. 3 sided war one side can dominate but it exposes it's flank to a 3rd party, which can capitalize on that exposure and negate any territorial gains. You can't have the game play it the way you want it played, and you cannot balance it unless you dictate side balancing, so you must have a method to allow the dominant party to have it's exposed borders attacked forcing a defense. If the 1st countries exposed border isn't defended, the 3rd country will capture fields as fast, or faster, than the 1st country which will cause them to weaken and fall, allowing the 2nd, the once weakened country, to counter.
This condition is impossible with a 2 country side. Just because the Players don't take advantage of this does not mean the system is a failure.
2 sided war works in Structured Events, with objectives, focused plans, focused missions, and aggressive guidance from a dedicated command staff. This will never occur in the Mains. A 2 sided front allows for unrestricted domination by one side, a 3rd country removes the "unrestricted" element. Now, arguing that 2 sides can gang up, or one side is too low number to effect change, that's subjective and player issues to solve, nothing at all that can be coded out of the game.
As for the AvA not being melee, I get what you are saying, it's an Axis Vs Allies arena compared to the open, free for all Melee arena in the Mains. But that has nothing to do with the 2v3 side discussion.
