Noted.There is no need to look at ALL the games 11. A lot of players wouldn't trush in arena by default because (i) its really really boring (ii) it's not the point of the map. The reason you start with stone walls is "hypothetically" so you can skip dark and feudal age aggression. 900HP walls doesn't allow it given how fast villagers break it down.
What you need to look at, is players like Vinch, TaToH and St4rk. Their win % using it and the maps of their opponents when they lost. Absolutely phenomenal players, don't get me wrong. Would they have gotten their final placements if walls were the normal 1800HP, I don't know.
Will keep that in mind while scanning games.
Thank you,
