What about Ji-kun?One - Surv is same strength if not better than BM on singletarget.
Two - there's no fights this tier that benefits BM more than Surv. Jin rokh's pools lines up badly with BM's burst, and every single other fight favors AOE/Multidotting *heavily*.
Also, GL using the rep trinket with my levels of hit and expertise. So many wasted stats.
As for Barrage, so far found it a dps increase on Horridon, Council of Elders (assuming you hit all 4), Tortos and Magaera.
