Does anyone else hates playing space marines against space marines, eldars against eldars etc? I do. I hate mirror matches, they are dumb, they are boring, they are awfull and they happend too often, like 2/3 of times (1v1 mode). I haven't found any way to avoid that, i have to leave game when opponent prepares to play same faction.
Relic, you should add button that disables/enables mirror matches like turn off/turn on (at least for 1v1 which is only competitive mode). So playing mirror matches will be optional. I am really surpriced that you still not have done that.
