For u mr.sloth, its been awhile since i played d2,so sorry if i get minor things wrong,like skill names etc
For your melee enchantress(assuming u want pvp)
Stats-Enought strength for gear
Dex:try to get enough for max block with SS,if u dont wanna waste alot of dex,use the rune in the ss that adds 15% blockage(i think its eld or el)

Energy:enough to tele around in duels,along with casting enchant and some other skills
Items -
Shako(40/15 ias is good)
Valor(+skills is nice,along with the hp)
Sojs(adds mana wich is nice,the +skills is god too)
Ammy: try to get a rarw +2 or 3 fire skills ammy, along with some resists

For you proto blade,fire sorcs are best duelers,assuming by ure post it seems ure not extreamly rich,so just try for the basic sorc gear,occy/shako/tals/etc and make a fireball dueler
