Outsides? That's interesting. I use the core for cover usually. Will have to try it.

I use the outsides because it's easy to take care of the ads when they come. With my friends we tend to "distract" melee bro by trading him off to each other. Whoever isn't busy with being bait is knocking down ads. When they tag team, we do the same strategy, except we take care of melee bro first. Obviously it's a little bit harder to stick to the outsides at the end so it's more of a constant rotation.
