OK, I am no expert on skills ands setups, but my build seems to work fine for me in T4
7700 armour / 1080 ar / 345k life / 7.7m toughness / 30k healing / 26k lps (with my ring ... up to 45k lps)
7400 armour / 1050 ar / 323k life / 6.5m toughness / 35k healing / 29k lps (with my ring ... up to 51k lps) 4 piece BT setup immune to some nasty ground effects
Both setup has +66% to lightning dmg, some +% to WotHF and LTK
BT setup is easier against elites with ground effects, but takes a little longer to kill
For T1 and T2, I use Overawe and only about 12k lps
Key for me in higher Torment lvls is healing, LPS is very important to me.
I can tank T4 Butcher with fire under me.
I don't take many hits with my sledge.
Monsters are stun most of the time, range monsters hurt me more.
Basically, I jump into crowd ... pull, wind, palm, ltk ... boom all dead.
These are probably not the best skill setups, but works for me.
Working on cdr monk, waiting on a few more pieces.
