I'm quite sure that it's defence that needs to be nerfed, not accuracy buffed. Most of the spec weapons while dhing will hit 0's 90% of the time, besides ags - like 75% of the time a 0.
Edit: I haven't been doing much other PvM bossing, but after the recent combat changes, infernos zuk phase seems at least twice as slow as it used to be. Anyways, pali needs to play around with the def/acc towards more hit potential, because I'm sure that people would rather hit more often than usual, than hit 0's and splash 24/7. (as long it's not like pure gmaul fights for dhers, etc.)
