Lets go through talents really quickly .
for first talent choice i choose Shadow Sheild coz i need sheild saved me a lot of times.
Second talent choice i pick between Immolation for a bit of pressure or thirsting blade if i am focused alot .
First Aid is no brainer here. better sustain .
Both heroic abilities can be used very effectively , but i use more often metamorphosis because i can combo it with other allies and to have better sustain or pressure
Giant Killer is for me here no brainer.
Here i sometimes use Second Sweep , more often Blood for Blood , Stoneskin is good as second sheild .
Demonic Form is here for me big plus coz i can than run around getting shutdowns on targets that are hard to chase .
