Okay yes there is a limit alliances option, hurrah. But let's be realistic, it will not stop ally fags. The majority of hosts will not use this option.
My proposal is this, people in an alliance are treated as one entity in priority. So if you had 6 players, 3 of them were allied against the other 3, each of the separate 3 players would have 1/4 chance of moving first, 1/3 next move etc. The 3 allied people would together have 1/4, but as individuals have 1/12 chance. This would negate what I feel is one of the biggest challenges against an ally fag, players can attack you seemingly simultaneously in the battle phase, whilst you sit idly watching your units get obliterated.
More players gives a higher TB chance, and we all know turn priority is the most important aspect of winning this game.
