The Cerberus Ajax Armor is one I recommend to any class. I use it for turning any build into a combat capable soldier. I usually stick with Adept for my love of the Throw biotic. But, Adepts have a certain weakness when in full combat situations. This may be contested, but I focus this on the Mass Effect 3: Omega DLC. The mechs in this DLC tend to be tricky as an Adept because of their armor.
