Guild Wars 2

One off event each year.
If you have a two handed legendary weapon, you can swap it with another player who also has a legendary two handed weapon.

If you have a main hand one,..you can swap for a different main.
Off hands can be swapped with off-hands.
Ambidextrous weapons can be swapped with main or off-hands.

It doesn’t affect the market, because the total number of legendary weapons doesn’t change.

This has been part of gaming culture since day dot. Players swapping games, cards, piece’s etc.

It would be a fun event that would help invigorate a lot of players into changing their mains and rolling with a different profession and getting some replay value.

Think about it. I am giving you pearls here.

I actually quite like this idea, like a second hand market for high value items. The only issue would be the wardrobe.

Nop , they don’t want you to collect free legendary skins.
