Well knowing how much you like pole arms, if you had Guild Wars Nightfall you could play a Paragon they use spears chants, and shouts to motivate and inspire group members. That's the closest thing to a pole arm in GW.

Otherwise Warrior/Elementalist is probably a good fit for you, go Air for lightning which gives armor penetration values, Fire for max effect area and burning damage, or earth for wards and armor buffs.

Water is lame, unless you want to maximize your ability to out manenuver your foe using ice to slow or isolate people.

I am Wrath, I am Steel, I am the Mercy of Angels.
mors est merces mea – death is my reward
morte in vitam non habet tenaci - Death has no grip on Life.
