Very defensive in the beginning. No one tries to take a look to the enemy fuel, but fights in the middle.
The enemy fuel is very far away from home on this map. When you know a 4v4 is going to be competitive, sometimes you have to bide your time to avoid biting off more than you can chew. Maxims can shut you down, force retreat, and you lose what map control you have.
It was definitely defensive, the FHQ on one side with mortars galore was tough. Have you seen the damage a maxim does with the buff from FHQ? This is a great ability when used properly, and it was used well here.
The middle is also a big control zone on this map - you need it to prevent enemy flanks, and setup your own. I'd say you need to control it.
