David it sounds to me that whoever you fought had absolutely no idea what they were doing except they were expecting you to be "just another warrior" who is supposed to drop dead unless he has 2 priests behind him...and why isnt warrior supposed to do that? If u run in to 4 noobs youre not supposed to do that because...? Its reserved for sins? ^^ If they had any idea in their brain that it can be different, and if they had any kind of tactic in fightnig you, you would be dead in a blink of an eye. But no, everybody knows "how warrior is supposed to be"...so they tanked you. Easy as fu**

I personally like the option to have passion simply because of the way i play. I rarely get to pk with "GG parties" full of GG priests. Mostly its either randoms or 3-4 ppl party who need to be tactical a bit, sometimes even solo and its ok untill i get duffed (and i never PKed with a clan that can form 2+ organized parties).
Its simply a different job for warrior, its not overpowered because you loose a lot od AC to get passion skills (this is from a "general pk" point of view...i dont give a rats ass about VS because i consider this a party based game)
Defense warriors are even more annoying and tougher to kill in general pk because of higher AC and descent. At least passion warriors cant run away

Oh yea, and btw, your brother...he can use 70 Attack / 80 passion, so he can use howling sword.
I tested all builds, but the best one for me is 85 attack / 50 passion / 5 defense / 10master...kinda gives best balance
But its just personal preference
