It was a handicap game, jh_dreemurr had a build power energy and metal boost this game, because you both had handicap activated and hes lower elo at the time of the game, and yes, handicap games are no elo by default.

hits on shields drain enemy metal via lost eco so every time you drain shields its as if you killed a flea.. not great i guess but the shield player must make huge amounts of extra energy to cope with the drain so if you can find the fusions you can destroy them.. also because of this shield players find it hard to push out sometimes until they get strong energy.. you can use that window to out expand them.. if your being shield rushed and cant get around them to hit enemy power then you could try skirmisher spam such as recluse to drain the shields.
