>>2116661They've made weird choices regarding the autoqueue. It has some advantages that were never there before like queueing up research (or even age up) as soon as you have resources, but the way it worked in original game was a repeat queue meaning you could get a mixed comp out of one building. Now you can only do it in even amounts (or whatever gets resources first), admittedly a minor thing but weird they felt the need to change that.
And that's assuming military autoqueue is on, which it is by default for the "casual" game modes, but not in ranked. For some reason, despite the fact repeat queue has been the way AoM was played the whole time they decided to try to appeal to compfags coming from AoE2 or other games and both players have to agree for it to be on. There's a checkbox for it I think, but it's off by default.
