Personal - i am a Fan of FFA Games. I call this - living stategie instead of the very statistic 1v1 calculation games. There is no ladder for FFA and quite often you find only Beginners to join the game.
Sorry about that ... because this games can have much more dynamic than making complicate 1 Unit movements all over the map only to get the last attack.
At least it would be great if Defensiv and Offensiv Kill rate are the same as Standart.
