I usually don't like giving my builds (cause people later say that they made the build), but I can see that many warriors have a problem beating the norn tournement/Bison.
Well, from memory here it is: (can't acess Guild Wars at the moment)
W/Any
Str 9 + 1 =10
Sword 12 + 4 = 16
Tactics 9 + 1 = 10
Any sword and shield will do.
The Build:
[E] Dragon slash
Sun and moon slash
Flail
"For great justice"
Enraging charge
Lion's Comfort/healing sig if you don't have it
"Finish Him"
Any Skill, Watch yourself/Dolyak Sig(not as good as WY cause of lion's comfort)/Riposte is nice
How to Use the Build:
Now, so far I have been able to take everyone except Eve (damn blood)
Ok, when you start the fight activate "For great Justice" and Enraging charge, this will give u 7 adren right off the bat.
Activate Flail and spam Dragon Slash and Sun and moon slash, they recharge instantly when "for great justice" is on.
If you start getting low on health use your healing skill, no duh

When "for great justice is charge again activate it, during the time its charging you can use enraging charge for adrenaline.
Now when the enemy is below 50% hp use "finish him", the damage,deep wound and cracked armor(I think it give cracked armor) will bring almost everyone's health to 1/4 hp.
When you get to Bison do the same thing, but you might want to take Riposte instead of the defence skills, because then you'll be able to block some of Bison's powerfull attacks.
Well that is pretty much it, if there is degen usually you might die after winning but that doesn't matter at the moment, unless Anet changes it that you lose if you die after you win.
Hope that helps, if you still have trouble contact me in game.
