Soo ive been doing alot of testing with dark fury and force lightning.. ive notice with or without dark fury at rank 3 frs its a 3 second cooldown period on force lightning. I have also noticed force lightning is capped(at my rank atleast) at 5428 damage unless you roll a crit and is garunteed to miss 2 out of 3 times 95% of the time the other rolls being RNG... maybe swap out on dark fury the cooldown reduction on force lightning to a chance to hit bonus with lightning to fix both? Also force shockwave either increased damage or removed from dark fury and swapped with force drain or maelstrom.
