Yo, those builds up there are somehow weird. I wouldn't go paired weapon, for pvp you would dissapear in seconds if you are fighting a warrior or a palladin since they have more buffs than wardens. Wardens have become squishy-casters, not tanky-melees. But that's just my point of view.
Yes and no. Wardens have a lot of rubies to survive. For PVP I'm taking all healing, dodge, armor rubies. Still, if you go to AOD it's hard to survive (unless you have a personal healer, then it's OK), but in 6v6 Dominion you can be really tanky. With paired weapons you can spam Hawk's Strike and its healing depends only on your wand and stats, not on the cooldown of the skill, which means that you have a built-in lifesteal. Also Bark Shield is really nice to survive burst, but you need nature's balance ready for it. If you see that players are focusing you, pop up Bark Shield and then don't use any potions until it ends (NB is the exception). Use all potions after Bark Shield.
Finally, I was able to win a lot of duels, with warriors, mages, paladins, summoners, scouts. Only psionicists were impossible to kill (twin and I can't do anything, because either me or my pet couldn't see it). Also duels against FH were a draw, unless I got a rage potent and drained his mana to minimum and then used Aqua Morte to finish him. I haven't been a huge fan of WH or DF, I don't like playing PVP with players who can't hear me and that I can't hear them. That's why I was playing mostly Dominion with my guid and everyone on Mumble.
Anyway, I'm not playing Allods anymore. I've been probably the only warden using paired weapons. I've played like this for over 2 years and never wanted to change to any other weapon. I did all the hard stuff, like TP, MA 41+ (stopped playing before fabled upgraders). Since my latest build is still working (only some stats have changed), I'm sharing it so someone might use it
