Cant believe you didnt close this game out. Late game PG spam can be kinda sneaky, I find myself never being prepared for 5 extra PGs hitting the field 30 minutes into a game. I think what you needed in this game was a handful of extra flamers in the mid/late game to help you stand up to all them PGs. You had all his vehicles dominated already, just needed support against the 9 PGs on the field.
