While verse is great...I'm pretty sure theres a lot of warriors that will disagree on crit/haste.
Well, yeah I'm sure there are many... all I can say to that is that they're wrong.
Fury warrior with the talent "War Machine" and the gnome racial & swiftness potion don't need haste or crit, Strenght & versatility makes your rampage hit so hard that you can global any DPS no matter how amazing their gear is, you don't build your fury to have fast Rage regen, War machine on it's own is enough. (also, autohits don't deal a massive ammount of your overall dmg aswell)
So far I haven't been outdamaged by a single warrior in the bracket, I saw some Crit/haste warriors and I had a 20k+ dmg lead at the end of the BG, It's not a matter of skill or xp, just a matter of choosing the right stat and using the talents/engineering items & potions in the right moment, on paper haste sounds great, but in practise you really don't need it, the 1hit/global mechanic of fury warrior is enough... If my opinion is worth anything to you fury warriors out there, build your char on DMG purely and you will completely dominate the bracket.
*potions and engineering items are still needed if you play without perso-heal tho
*the "skill" about fury warriors on this level is :
1. Rage management
2. Engineering usage
3. Potion/flask usage
Frag belt greatly improves your Fury ( I have it )
It makes you win 90% of duels simply because you have a kick, Stun or DMG on demand... without it you should still play with bombs.
fury can be the most insane DPS in the 20's bracket, to me it feels like one of the strongest classes in duels and BG's.
