Summary:

This build focuses exclusively on punching people really hard as often as possible, with the focus being on extra melee damage and recharging Berserk. All explosive skills are ignored, as well as most of the damage bonuses. It's pure tank/punchy goodness. Great for first playthrough, especially in conjunction with a warmonger mod that gives damage bonuses. Given that explosive skills aren't used, a good combat rifle is a must for long range damage.
