Guild Wars 2

Do you want Ascended Gear to have changeable stats?
Yes? No? Why?

In the future, they will make Legendary weapons to be able to change the stats to all possible stats combination while out of combat. Why not let Ascended Gear change stats as well? However, the gear with the other stat combination must be crafted first before it will be made available for stats changing purpose while out of combat.

For example,
Deimos crafts a 1st Ascended Amulet with stats:
[Soldiers]
[Soldiers]
[Defensive Infusion]
This 1st Ascended Amulet has only 1 stat combo in it.

Deimos crafts a 2nd Ascended Amulet with stats:
[Berserkers]
[Berserkers]
[Offensive Infusion]
This 2nd Ascended Amulet has only 1 stat combo in it.

Deimos now combines 2nd Ascended Amulet into 1st Ascended Amulet via crafting.
2nd Ascended Amulet is destroyed in the process.
1st Ascended Amulet now has 2 stat combinations.

Legendary Gear will have all available stat combination, and newly added stat combinations will be added to the Legendary Gear too, since it is Legendary.

Ascended Gear will require stats combinations to be added one by one.
