Here is what I'd run on a budget. Accolades are turned on as they are free and help with end. End still looks high on paper, but mids doesn't take into account the three performance shifter procs or the end from the panacea proc. You're end should be fine. Have musculature t4 turned on as well. Could always switch to other T4 musculature and sacrifice a lil dps for end mod.
Probably more expensive than your build but still no purple or snow sets. Having a couple snow sets would really change the ease of soft capping defense, but they are super expensive, of course. Would also likely get fire/cold to soft cap too.
