The Berserkers definitely looks like their gonna be a beast on the battlefield, with the added survivability that Heal gives them coupled with a Dmg buff from Rage. I can see them as very effective shock troops, sending in a wave of them and activating Rage right off the bat to decimate the enemy formations then almost when the battle isn't looking in the Orcs favor, Heal, they get a surge of renewed strength to push the enemy further back. Hmm...It'll be interesting to see who exploits that first. I can tell you whenever I get around to playing Orcs all of my attribute points will go into stamina for the berserker.
I've found it interesting to note that the Orc faction's units seem to have the highest Charge attribute of the units previewed.
