illusionz: for me:
[!] barb best build= pure dex (with supporting wisdom frm gears and runes over 250 widom at lvl 80)

[!] druid best build = pure wisdom (supporting dex from gears and runes) i personally doesn't like druids lol!

[!] paladin = dex and wisdom in balance.

[!] necro = dex and wisdom balanced.

with new updates lotta things changed, right now druids looks like the strongest to me since the new legendaries for druids are bad*** lol.

moreover with stat buying option, i'll say for each class go with dex and wisdom in balance!

illusionz: This is not my knowledge, but I'm finally posting it where I had hoped the author would post.

Every player does things a little differently, but this is some great advice:
