I have also swapped out BF for the Bells and I love it. I actually lol from time to time with all these jingle BELLS dropping, so fun. I prefer a dual wield vs skorn for the SW/Bells build, though I find myself using SW less than before (I farm mp5, and am looking to upgrade gear in order to try higher mp lvls, i.e. faster mp5 up to mp7). Here is my profile so far. What should I upgrade (weapons, I realize what I need but am having fun with the Shenlongs, and can't afford an EF + WKL + lifesteal just yet). Also, which slots should I *not* upgrade?
Most of my gear is self-found or crafted (besides blackthorne's + inna's). Found that int/vita witching hour and would love to swap it for a dex/vita one, but $$$. My budget right now is 35m, and have a $20 sale processing in the rmah, so + ~70m eventually

I still use cyclone as I don't find myself having many spirit issues (I also have a full TR gearset in stash - 4p innas + bad skorn).
That "loyalty fervor" ring looks bad, but actually adds upwards of 15k dmg and I'd likely use that as my nat's ring slot, but I'm finding I need a high end nats to fill that spot, or I want one at least

(nats + os + cd + cc).
Same issue with my boots. They seem pretty decent and the problem is that I don't want to drop mass igg on nats ring/boots only to find that I was better off before.
