Seems to me like the Legacy of Nightmares is the true gem of this patch. It'll allow for crazy builds and setups to work when they shouldn't, not just roll with whatever 6p set you have.
LoN takes way too long to get started though, you need to farm so much before you have a decent LoN set. And even then it sucks for a bunch of classes.
I tried LoN Strafe on my DH but it looked horrible. Granted I don't have optimal rolls on my ancients, but I still had all the "right" gear with a few decent pieces(really good magefist, good cindercoat, one of the crossbows is good other is meh etc), and it was struggling on T10. I guess the main issue here is Strafe sucks, but if you're not using strafe, then it's not gonna be better at doing multishot or cluster than UE/Marauder, so... Rapid Fire maybe but I don't have the ancient version of these, only the 2 strafe xbows.
Now if I was another class, like say WD, that'd be a different story, but the set just doesn't work well with some classes.
What I really like about this patch is I'm about done with the season journey, and I've done 4 bounty runs total and didn't have to farm RoRG. That's such a nice change. I mean some classes still use RoRG, but it's great that it isn't necessary anymore. Although I'm probably going to end up farming one so I can do my wizard set dungeons since I got all 5pc sets.
