Scaling of Old Gems

[Ebezaanec]

So what? Many discontinued things are carried on...hmmm
Heraldics? Why not just delete them all from the game ? They are discontinue but continue to circulate and are always on the market...let's remove all of them from the game!
No...same priciple...different item...

A heraldic or tabard or crier does NOT have the same effect on gameplay as gems do. They are nothing more than vanities. So not quite the same principle.
