As for my (and others) ideas not on this post.

A. Item preview - Allow us to see what an item looks like on our character. This is an RPG, I want to be able to SEE what my character can choose to look like when thinking about choosing loot/rolling on something/crafting. Top priority for me.

B. Allow Mailing to your alts... I know people are worried about items stuck in mail for storage purposes.. but.. it is REALLY hindering gameplay for people with multiple characters...

C. Allow people to change class/jobs during a dungeon etc IF someone leaves the group. It is incredibly frustrating sitting there waiting on a healer that never comes while the dungeon sloooowly times out, and you sit there having a perfectly good healing class out of reach. Could not be abused, restrict it to only being active while short members, and out of combat.

D. Tab targeting options allowing classic tabbing order, not just forward/reverse indiscriminate of distance.
