He switched to Sever a few days ago so we could do some DH-Barb runs and test the mega-crit-die-all farm build, and we both noticed that "stun is no more".
Would you be kind to confirm this to me as well ? I do not roll a Barb. If two players can confirm this, than I'll ask my friend to open a bug report to Blizzard.
I've never tried Server, although I just bought one for cheap so I may test it out.
