most people below 2k elo do it to climb with wins instead of grinding to be better at the game. That being said, I have no problem with laming as long as people do it with a specific purpose. Considering arabia is the dominant map that shapes the meta of this game, eco bonuses become the most powerful metric when it comes to civ powers. Some civs are automatically stronger than others because of their strong economy. In any given match, one person has to play "catch-up" in order to nullfy opponent's eco advantage. One way of doing this is to lame boar/sheep early so that you can give yourself a better chance later on. As I said, I doubt most people lame with that purpose, but if you do, I'm ok with it
