Here is where I stand now:
I previously had the same stats but with 149k dps using a blackthornes amulet instead of the one you see in my profile. At mp 10, I could handle reflect by itself and electrified by itself but together they have become my nemesis with my current damage mitigation. I also found that if I was tanking an elite pack, ranged attackers had become a real pain also forcing me to teleport on top of them to kill them before returning to the elites. I was in need of more damage mitigation but I also wanted more dps which would need even more mitigation from reflect packs.
I ending up buying an amulet that added 37k dps. What this means is that at mp 8, which I think is going to be my optimum gear farming level, trash and elites die very fast and I can handle reflect + electrified with the help of teleport safe passage.
So when it comes to mp 9/10 uber runs, I use crystal shell instead of diamond shards. It greatly increases my damage mitigation to the point where I can keep absorbing multiple butterfly swarms from magdha. It also allows me to effectively tank reflect + electrified packs on mp 10 without dying.
This all brings me to my current question. What is your effective dps using SNS? No glass cannon or magic weapon. Currently, I have killed mp 10 ghom in 118 seconds using crystal shell (95 seconds with diamond shards) instead of diamond shards which works out to 1.1m dps assuming he has 138m hit points. I believe that puts me on par with someone who has 150k dps but uses proper SNS skills.
What I am hoping is that this huge jump in dps has allowed me to use crystal shell but still maintain dps similar to the 150k I had previous with the blackthornes amulet. Increasing my mitigation and still maintaining my current CC, APS, DPS was going to cost a hell of a lot more than the amulet did. Unfortunately, I sold the blackthornes amulet so I am unable to do any testing to compare with.
