Asherons Call: QotD - What Would You Like to See in Tinkering?

So, suppose you could have anything you wanted in tinkering. ANYTHING. Not just "add one level of blooddrinker" but say...

[li]A tinker that costs 3 tinks but changes the racial requirement?
[li]One that costs 5 tinkers and counts as an imbue but adds a minor spell to jewelry?
[li]What about lowering the rank requirement?
[li]Lowering the Arcane requirement?
[li]And what about Armor? What would you want to see on armor?
