Warrior
TitanThey say the following about the bear colors:
"If it's black, fight back
If it's brown, lay down
If it's white, say goodnight"
BIG ICE DAMAGE, everything shatters!
Using Embitter and Cold Attunement on 
Rampage/ 
Furious Slam/ 
Walking Calamity combined with 
Polcirkeln turns most of your damage into cold damage which chills enemies which then instead of chill instantly shatter!
This solves the problem of your bear constantly getting stuck, allowing smooth gameplay. (most of the time!)
Pretty much fire everywhere but it stays cold.
Constricting Command allows the use of the surrounded nodes which remain strong, get one with 4.
Astramentis is very useful early on to not have to waste all your stats on dex/int. 
Defiance of Destiny is insane defensively.
Morior Invictus fixes all your resists, get one with chaos resist, elemental resist and flat life.
For your talisman get one with as much as possible attackspeed/pdps!
I am a huge fan of instant leech, its a great defensive layer, combined with Cannibalism II you will mostly always be topped off.
Get this on a 
Heart of the Well!
