It depends. I'm a pvper , i don't touch pve and i believe nothing much changes from 5.4.2 except for dampening and other stuff .I would rather get very important fixes like: hit rating, force of nature for druid,fix whatever the f is happening with those 100k+ slams, fix mw monk healing and druid healing (its too freaking high) and the damned psyfiend that fears through pillars from africa etc etc
