in my experience, javazons have never been powerful in classic.
but if your really wanting to make one...i would suggest the following:
Str: enough to use gear
Dex: Enough to use gear
Life : Everything else
Mana: None
Helm: something with FHR/life/dex/mana/str/2-3 different res's (socketed w/ ruby)
Amulet: something with +2 amazon skills/+str/dex/life/2+ res's
body armor: something with +str/dex/life/fhr/2-3 res's
Weapon: the best javas you can find of corse... preferably with good IAS
Ring1+2: SOJ
Belt: Rare FHR/life/dex/str/2-3 res
Gloves: rare IAS/str/dex/2-3 res (or frosties possibly for extra mana)
Boots: 20+frw/20fhr/dex/str/3 res
when gathering gear, i would go after as much fire/cold/light res as possible.
as for stats, im going to assume its still hard to get past 86 in classic, so lets say youll have 97 total skill pts to use (this is including all your +skill quests)
Lightning Bolt: Max
Charged strike: Max
Lightning Fury: Max
Power Strike: Max
1 into dodge
1 into evade
1 into avoid
13 into crit strike (cant remember, but i believe crit strike works with lightning attacks, if im wrong then dont use crit strike)
the rest into lightning strike
