I feel like Mara/Sent should have another one in there but it's the only class I haven't played to 50.
Any help on that one? Force scream w/procs? Last hit of Ravage?
Annihilate is probably 5K capable, although my mara can't because he is undergeared. Need confirmation.
As for Sorc, my bro played Lightning Spec at the beginning and according to him, Chain Lightning (and maybe Thundering Blast) tend to hit harder than Death Field... so if Death Field is 5K capable...
