So what is everyone's preference on capping expertise for PvP as ret? I see some who don't care for the 20 expertise while other's say it's mandatory. I get a lot of mixed responses.. Personally I cap it to avoid my CS being dodged/parried, although there is that ability for people to still do so. Can anyone give me convincing advise as to why capping expertise is a GOOD or BAD idea for arenas?
