but WHY have gamers THE wish to build up a "pure" warrior ?

The fact that people keep saying it is so hard is making me want to try it.

Wait, would Mana Efficiency and level 1 of Healing disqualify the 'pure' label? In D2:ED with my strength based duel wielding warrior and DKS with my ranger, I invested in Mana Efficiency so I would not need to boost Spirit or Intelligence in order to summon the creature and have enough mana left over to use special skills.

In any case, I've been planning on playing the PC version with an unarmed warrior, once I build a new computer (which I'm not in a hurry for; I won't really need it until D:DC and D:OS are released).
