I know this quote is from a while back but the thread got bumped so I was just reading it. Not sure if something changed, but I was questing with my Act V merc last night and he finally got high enough dex to wear the LB PB I had on switch, and with this thread fresh in my mind, I was paying close attention. There were definitely situations where I saw Taunt overwriting Decrepify. Overall it wasn’t a big issue since things were still dying quickly (with Sabazi and LB-PB and me with Oath/Fant damage output is pretty good for where we were in P1) but I could see it being frustrating in a harder fight, or if decrep is breaking PI then it gets over-written, which is something I think I saw once or twice also.
I also looked at this. I didn’t do any actual testing, though, but the character sheet damage was definitely less when I removed head striker and left my frenzy merc with just Sabazi set. The hand that the Sabazi sword was in didn’t change, but the head striker hand dropped down (to whatever base damage he would have w/o weapons? - I should have removed both to “test” that).
That said, the character sheet from mercs has been pretty buggy since D2R release so my observations without actual testing are probably not very conclusive. I guess the title of the video is that they fixed it, so maybe that is expected after all now?
