The other day I got the T5 gloves token off Leo in SSC. I already had my T5 gloves so I got it with the intention of turning it into the PVP gear vendor at Quel'Danas for the S2 Merciless Gladiator Gloves. After doing so I realized that I already had the S3 Vengeful Gladiator Gloves. One thing to note is that turning in either a T5 token or a T6 token still gives you the S2 gear.
Therefore, since T5 and T6 can be turned into S2 gear, I got the S2 gloves. I then put in a ticket claiming that I had accidentally turned in a T6 token for the Merciless gloves and meant to get the T6 gloves. After a while I talked to a GM and explained that I turned my token into the wrong vendor. The ticket was then escalated. 5 days later I got an in-game mail with my T6 token in it! One thing to note is that this does use one of your item restores that GMs will do for you, so be careful if you have had items replaced before.

Quick Summary:
1. Get a T5 token from SSC or TK.When I tried this I didn't think it would work because I figured they might have a log of me turning in a T5 token, but perhaps because a T6 token can also be turned in for the same reward, they believed my story and gave me the token. Let me know if anyone has had similar success.
2. Turn the token in for PVP token at Quel'Danas vendors.
3. Put in a GM ticket stating that you turned in your T6 token into the wrong vendor.
4. Wait for GM to send you a T6 token after a few days via in-game mail.
