I rather enjoy being a brute too. I am level 25 and Dark Powers/ Dark Melee.
I am not very impressed by the inaccuracy of Shadow maul, it misses quite a bit even with 2 +30% DO's slotted. However cloak of darkness, siphon life, dark consumption, and dark regeneration are all very fun to use against a foe, especially when you have the ability to teleport your foes right next to you :-D.
Getting in the iddle of a mob and maxing out ones fury bar is Awesome, with my fury bar maxed out each punch dealt in shadow maul deal 27 damage, and shadow maul hits a foe about 15 times per use, so 27 x 15 is the amount of damage it deals to the target when it lands. Not to mention shadow maul is an AoE cone melee attack so if the target has other foes behind or next to him you are also hitting them as well.
The only thing I don't like about being a brute is the lack of range, but that is easily fixed with teleport foe.
Just the other day I was PvP in bloody bay and a hero was running away froma mob of us villains, he was sure to escape..... and then next thing he knows he was teleported right into the middle of us and we ate him alive. Gotta love that Teleport foe. :-D
