I want to see interesting cursed items that people will want to use.
I would like to see interesting intelligent items, that are not just a rehash of older editions.
Items that are class and race enhancing, like rage weapons, monk hand wraps, belts of dwarvenkind, stuff like that.
I would like to see the returning ability to be default of all thrown weapons, and ammo creation the default of all magic ranged weapons with that property.

I don't want to see anything that gives a static ability score modifier (unless things change from what is in the Basic version I highly doubt this will happen), but most of all I don't want to see any magic items that give an ability score higher than 20, like belts of giant strength did in the playtest.
I don't want to see weapons of sharpness or vorpal, chopping off limbs is not cool and defeating a big bad guy with one lucky roll is anti-climatic.
Another thing I don't want to see is magic armor of the following types; padded, leather, hide, chain shirt, scale mail, or splint.
Why because if you have the time, energy, gold, and power to enchant a suit of armor why on earth would anyone enchant one of those when they could spend some gold and get a better type of base armor.
DM: "You find a suit of magic leather armor +1"
Player: "So basicly studded leather?, great I have had that since first level, these magic items feel ever so 'magical'!"
