Imperial Pike Guards
Meta Vet + Build
You essentially want to be tanky with these guys and provide the damage with their doctrines. They grab all the important nodes when going bottom line, only thing you'll be missing out on top is the +1, which shouldn't matter that much when you have a team to help back you up, as well as Advance not being affected by the node too. Last doctrine is supposed to be the Lifesteal doctrine but the website has yet to add that yet.
