Ok, I'm going to be a little negative with you. I know you spent a long time writing this up and I know how it feels when someone bitches about your guide.
I made a guide in another forum strictly on z v a.
My zon is here
http://forums.d2jsp.org/index.php?showtopic=3413770&st=0if you scroll down to the bottom, you can see the stats with bow out. With sheild out, my build has at least 40+ to all resist with minorly stacked cold resist. resist is important for z v a. You can also notice I do 7k damage with 1k life. Using legit charms.
I'll tell you right now passive gcs are bad. Im guessing your build has around what less than 500 life?
penetrade doesn't do much. Get slow missiles.
lightning bolt is a must. Some people said LF is the winner? LF can be blocked so any smiter will rape you.
don't waste a point in strafe. Multi works better.
Your passive skills are messed up.
max evade- you're running for more than 75% of the duel. You wouldn't max that?
max avoid - your chances of winning against a projectile is the highest. Secure it.
get dodge to 50% - Its real simple. 65% or 50%, you're gonna be dead if you get hit by more than 3 times with a ww barb. With your build, I'd say even 1 hit could kill you. All about skills.
your strategy is all off too. You spam multi too much. Multi doesn't track anyone, it costs a lot of mana, AND it does way less damage than ga.
for example, good fire sorcs will tele on you and then spam. Fire is one of the hardest for a bowazon. Lite is second hardest cause they have high es. Blizz isn't easy either. Orbers, you stay in the same spot and name lock them
For hammers, you don't spam multi while they're coming at you. You GA until he gets close and run, ga, run, ga, run, ga. Or else he will kill you 100%. You'd beat most "noob" hammerdins or hammerdins without max block but if you stand still as you suggest, you will die to all godly ones.
Barb... You can't tank a barb. namelock guided? Are you joking? True barb will get hit like 2-3 times but you'd die right after... ga while he is teleing towards you. switch to sheild and walk. LB him and if he's stupid and does a long ww, take out bow and ga. He'd die after 2-3 times of this.
you also forgot to mention you desync at 150 frw.
n2b guide. I don't doubt you're going to kill mf sorcs and mf dins but you're gonna have trouble killing half decent chars with this build.
