NOT worth the effort. It's weak in both PVE AND PVP. Take it from someone who's done the grind. Rodrix broadsword is mediocre, especially considering the amount of effort it takes to earn it.
It's not that powerful and it's suuuper slooow. My opponents are constantly getting away right when I've got them on the last sliver of health, or they get killed by someone else. And the sights are poorly designed.
I get muuuch better results from Bygones which isn't even masterworked.
The only thing Rodrix has going for it is Desperado and outlaw, which increases the rate of fire and reload rate for a few seconds after you land a precision kill. It's a nice perk but it runs out so fast it rarely gets any use.
