Feedback:User/Rose Of Kali/Binding exclusive rewards to the account

Problem
There has recently been some controversy about players who sell "exclusive" contest rewards, like the Everlasting Henchman Tonics, Miniature Mad King's Guard, and many other older rewards. These items are extremely rare and are meant as a special reward for something. Many players argue that these items should not be tradeable, but stay in the account that acquired them in the first place. The reward is not meant to make the winner into a mill/billionaire via trading for stacks of ectoplasm and armbraces, it is simply meant to be exclusive and special.

It maybe already too late into the GW1 game to change something about how these rewards are given (I made this suggestion for GW1 at Binding exclusive items to the account), but GW2 is a clean slate so far, so this is very much worth considering.

Suggested Solution
I suggest making these rare items into  special command items, such as the Igneous Summoning Stone, for example. These items are customized upon spawn, and cannot be traded or dropped.

Obviously, we don't yet know if such a command will exist in GW2, but this gives the genaral idea of the suggestion, as I'm sure GW2 will also have such exclusive rewards.

Furthermore, this would give an extra convenience benefit of being able to spawn a copy for each character on the winner's account instead of having to pass the item through storage every time when switching characters. It can also be destroyed to save space when needed (or by accident) and respawned again, so it cannot be lost for the life of the account. As a side-note, this implementation would also mean that they cannot be stolen in cases of account hacks. This way, the winner gets to keep their special reward forever, and cannot trade it to become instantly rich instead, while caving into the greed of players with lots of money.
