in my opinion, there aren't any particularly difficult factions to master. you can develop any of them quite well. each has its own unique features. I think that a beginner should "experience" each faction (play enthusiastically using only that faction). then, later on, in online play, it won't matter to you which faction you play as)))
And how many games do you need to play with each faction to learn how to play well?
That's a lot of time.
We're waiting for your expert opinion after you've played a hundred games. Are all the factions really that equal, and is it really "all the same"? :D
За то что нейтралы не бегают за единичкой, для меня это уже стоит того
