Itemization should be first because they have added new content has been added. Why ask for an expansion that they can apparently use to make the game just as bad or worse than it was released and patched and you have to pay them more money. When they can just release patches that are free and paid for by the RMAH and purchase of the game, that did not have all the content they claimed and didn't deliver yet.
They have already stated previously that they will not charge for an xpac. And if the community asks the questions like this..
if you guys keep being vague about 'itemization' you will get vague answers and vague promises
i say shoot for one things first.. make all elemental damage do unique things besides cold
start from there and then itemization can take root and then do another phase, etc
with no focus there is no goal
Then we will get what we get. You have to be more specific. You can't go to your doctor for massive chest pains and only tell him you "don't feel good" and expect him to make a proper diagnosis.. Once he knows the actual problem he can put together a treatment plan that will get you back on your way to feeling 100%. Or you can just stick to the same old "I don't like where itemization is at" and have them fix it they way they see fit. But as far as the xpac goes, yes we should be looking for that IF the proper questions are asked and they are given the communities actual problems. But only when the itemization and loot tables are fixed.
