I had a feeling that what I said here was player error instead of a damnation of the build, so I kept going at it: my problem with Crucible is that I keep thinking that Vanguard banner is good. After sticking with it for a few days, I found that Aether Reap Spirits perform similar to my Chaos Reap Spirits; good enough for easy SR 65-66 running, and at least fast enough to perhaps get 100-150 Crucible, though I have an awful time fighting trash waves with a huge number of Hero enemies. Anyway, here’s the build post - hope it’s to someone’s liking.
