Not mentioned on the front page but worth noting nevertheless because this is pretty big (and good) change.
All Blue quality items made with crafting professions are now BOE instead of BOP
They also no longer require BOP cooldown materials. For example BS and JC can make blue gear (ilvl 535 - 585) using raw ores. It's 60 ore total per item - either full 60 true iron / blackrock OR a mix of 30/30 both.
Blue gear is nice source of draenic dust as well after the hotfixes. Spamming those may actually be feasible way to provide yourself materials. Good news for people that didn't dumped their ore on AH for 50 silver each. Now we actually have good demand for ore and spammable items to craft and sell / DE.
Also, this makes the JC daily quest actually worth doing. Before that, well... 10 taladite for 200 gold? Yeah, no.
