Desperado already hits above 12k using legendary gun and just a normal elemental bullet, and desperado hits at least 3 hits per cast, mostly 5 hits when the enemy is close. if you are using ghost element, that means double the damage against people who had GR armor. Seems to be too much.
shadow element, sure, I can agree to it.. Ghost element, not so much, might need some kind of tests first because I really feel the damage will be too much.
