I have this build. At first glance DPS looks shitty. But it has 4 DW nukes - Primal Strike, Sudden Strike (rune on medal), Execution and Amarasta’s Quick Cut. It can do SR 65-66 OK. It can kill Grava in SR in reasonable time as well. Depends on whether you want more and this is not enough for you. I am satisfied with Stormrend as is for the PS part. I would not be against adding AS on it so that it can be better used with spam PS as well.
