@atomicpunk Doesn't decrepify make you run slower, so you already have slow WW when you are decrepified in chaos? If you say that FRW is super nice for WW barb, then why don't you use enigma and some other FRW gear? Actually i don't even know what your gear is, so maybe you can make a write-up about this barb, cause he seems really cool and interesting. I would love to see how you built and geared him, you know some screenshots etc., cause as you said, you don't have YT channel, so no video for us.
P8 chaos runs done in 15 minutes seem like a really awful thing to do and getting to 8/9 minutes per run with top gear doesn't make it better imo. I am not a HC specialist, i am not that much experienced player even, but i think there are better ways to lvl up a barb, if you want to lvl him up of course (I am currently lvl 98,7 on my SC barb if that changes anything).
