Best build/class for Beyond league?

EWhats the best class/Build for Beyond? one that kills fast but has great survability

anyone?

I got to level 85 with my cold crit/mana life leech shadow. Lots of survivabilty once i got six linked. Could many times facetank even beyond packs.

Used Ice spear, cold snap, frostbite, ice spear on totem, Vaal disicplin, hearld of ice and lightning warp.

Best char i have ever had, Sadly my Internet connection broke and he died :(
So your never completly safe..

Some gear :

witch and shadow.

But what build ?

you just want a cookie cutter build to go after?
yeah, wo don´t want to have such a thing

my top favorits are

molten strike build with max block/and 38% spell block, full resi, IR, unwavering, 200% life, about 5-7k dps

witch - arc build, full block/spell block, mind over matter, artic armor, 3,8k life, 2k mana, 5-10k dps depending on gear and level

both made it up to 70s and then died because I wanted to know the limit of tankyness. guess double dominus face tanking is not a good idea
