I am not a huge fan of the Vanguard class overall. But I was suprised we didn't have a Krogan Vanguard from the start. I am curious about the Batarians and the Justicar Adept.
I managed to get some unlocks finally. The Viper Sniper Rifle, the Phalanx Pistol (Carnifex I want), Tempest SMG (want the Locust), and got the Mattock and Revenant (rather have the Phaestorm). Kit wise I managed to only unlock those I wanted: Quarian Inflitrator, Turian Soldier and Sentinel, Drell Adept, and the Salarian Engineer (my favourite). Still missing the Salarian Infiltrator.
What can I say... I like the Salarians.
