Finally somewhere worth posting 
… Shame its rogue but im bored out of my mind 
Basically your a ranged fighter since you use bow, so do you need HP? And id recormend on amulet and ring, changing the +20% ED for +2All sets for a total of +8 inferno (id recommend less and using say vamperic touch and adding bleed damge into the build) substantially increasing damage.
Also on the other gear change the HP/ED% into blistering to increase damage even further.
Also test other sources of damage to increase damage further… This is a good method for higher quantities of damage and how good players deal millions>billions>trillions of damage… And if your higher in the scale of trillions then congratulations! You broke the game
