2.0 mixed setup (Barbarian, 2xWizards, Monk) and thougths...
Barbarian : http://us.battle.net/d3/en/calculator/b ... Yce!cZcaZc

Monk : http://us.battle.net/d3/en/calculator/m ... Vbc!aZcZZZ
The purpose of this is to benefit from multiple auras and complementary skills. This has been a good team prior to loot 2.0, and is still a good team now. Of course I can't have the Wizards perma-freeze everything anymore, but still.
With this team I can have very high « All resistance » and high Life Regen from the auras of the Barbarian and the Monk.
Also the reason I made this combo is the stun, incapacitate, drag opponents into AoE damage mechanism. This has been a well-known way of dps and XP since the early ages of online RPGs... BTW my Wizards stack 2 different modifiers on « Slow Time » so the team can have benefits from both +10% speed and +10% damage, and since « Slow Time » is permanent now (duration 15s and cooldown 15s), why shouldn't I use that ?
Unfortunately my dps has always been low, it's mainly because every good items I found untill now, I sold at the RMAH. It's fun how this paid me back for my Diablo III copies, IsBoxer anual fee, end even some of my gear upgrade ! But now with the AH closing (and most of the gear being bound to account anyway) I guess I'll keep my stuff. Right now I can run Torment III with no problem with only 100 to 150k dps per character. I'm not high in Paragon levels neither (110-120), since I have been mostly playing Path of Exile during the last months.
And then...
Despite my best efforts, I found out that magical damage from Torment IV and higher is absolutely unsustainable. Even with the Barbarian and Monk being in the 1200 « All Resistance » range, and Wizards being close to 1500 (due to high intelligence), there is no way I can survive multiple stacks of magical damage (which is not a problem in Torment III where I can basically be sitting duck and AoE dps), even with my Monk healing like crazy and debuf-ing opponents. And since I sacrified some of my dps on gear for some « All Resistance »... Finally I have bad dps and useless resistances.
Then I tried a team of 4 Wizards (the basic « Frozen Orb » template). With the self-buffs I can push their poor to average gear to 140-180k dps, while my « All resistance » is down to 850 approximately... but now I can run Torment IV with no problem. I eventually tried Torment V but it takes too long because of my current lack of dps.
What can I say ? It looks like Blizzard doesn't encourage us to think and build complex teams. Nothing's better than brute force after all.
