Necromancer+Barbarian combo

[Quillan]

The intention behind blind were that the barb didnt had to worry about being swarmed and pecked to death because of no armor when beserking.

Well, while that is fine and good, beserk is a poor main skill, and in your plan the necro would do nothing. Also, the barb would deal damage to just one creature with no offensive benefit from his 'teammate'

The suggestions i made (and the fellow pushing an avenger build team) will kill faster and stop monsters from being a threat at the same time.

I don't see the point of adding a 2nd char who does so little... why not find a way to make them work together and kill together effectively. Untweaked you could have 3 auras running with only 1 pally
might/defiance/freeze (don't use freeze if you keep a necro for CE)
fanat/conviction
or with 2 pallys add concentrate or whatever.

If you like necros, and i know i do, he can decrep or amp till the pally gets you a corpse, then CE them all. (CE's 50% fire would do even more with conviction, which the pally can change to as soon as a corpse falls)
I think that more synergistic duos are out there than beserk barb and dim necro, but give it a go and let us know how it works.
