I use thorn on my warlock and last word on my hunter, and at times i will switch to another legendary HC like Red Hand or my Timur's/Jewel to reevaluate my skills with the gun type. I even went flawless on widows court with my red hand because I felt I lost my ways using my thorn, taking a break allows me to get better simply because Thorn and the last word have very high RoF and everything else is lower thus making me focus more on precision
