No, to be honest, I don’t really pay attention to whom gives a heart to which comment
I don’t think it’s really that big of a deal. I consider myself a casual rts player and I have recently started aoe3de and I don’t usually have problems identifying units, except for some mercenaries and outlaws. I can agree some options like contours and other alternatives could be added to the game to make it easier, but as I said, I don’t find it that difficult, at least not more than in aoe2.
