1) It helps to say WHO YOU ARE in the match

2) I only watched until the t70s came out, but it did not look like you did much wrong at all play-wise.
3) Going penals and a sniper is probably meta for this map and may have served you better? The maxim has a narrow cone and the map is wide open, so the maxim will get flanked all day long. Since the map is wide open, snipers tend to work very well on it. Seeing the ass grens may change your sniper to a clown car if not too late?
