Well, the thing is that AoE3 cosmetic Event “still depend” on community matches.
There’s a bar that represents the number of matches played “without MODs” during the month.
If it doesn’t reach a peak number, which no one knows (but they say it’s 100,000), no one gets the hero. On top of that, you have to log in on the last day of the month when the bar reaches the top to unlock it. Playing the 4 matches indicated there is only an incentive to reach the TOP, but you can actually get the hero even if you haven’t played a single match if you connect tha day that the bar have a star.
I remember that when the first AoE3 event came out, by the second month no one could get the Mexico cosmetic because the expected peak (200,000) wasn’t reached. In fact, I even reported it: New Global Event: Unlock Hero Cosmetic
Let’s hope they lower the bar a bit for the AoM:Re event, just like they did in AoE3, because otherwise it’ll be pretty sad not getting the hero.
