I strongly disagree that chiv is useless in pvp. People just don't know how to utilize it properly :>
Bushido also is useful when paired with a chiv archer (Or fencer) and bushido/ninja based special abilities.
I'm bringing the necro dexxer back (people laugh until they fight it, then they cry for nerfs) and lately I've been running with a macer buddy of mine who uses 120 chiv, a war hammer and auto attacks for... well, enough damage :>
My next venture is the Necro Archer.
Swap macing for archery in that template, and you basically have the same template my buddy uses to great success. However for an archer it depends on what exactly you want to DO and how you operate as well as what templates you typically fight against. A run of the mill standard Archer Fencer (as Bodfather mentioned) is overall a decent choice for almost any situation as it plays to the strengths of most situations, group situations you can dismount people, disarm dexers who sit on your mages, disarm mages who use -mage weps over Wrestling or anat+eval. Other archer templates consist of the tamer archer and a dread mare (or bane dragon), the stealth archer, wrestle archer (Same as fencing archer you just cannot build hci/dci on your bow in order to be useful, but you can bait disarms for minimal dmg taken), the Tactics Mage Archer.
