After a hell of a long time of leeching TEH FORAMZ, I finally figured out an exploit which hasn't been spammed, reposted, reworded and reposted >.>, nor a 1-time-lucky-coincidence.
Firstly, earn a couple of arena points - that is - earn 1.8k points for say, the s3 helm.
Then go to the gear vendor and purchase the helm.
Post a GM ticket immediately afterwards, saying that you want REFUND (not an exchange) of arena points for the item you bought by "mistake".
The GM will request that you delete the item (go ahead and delete it), and will proceed to give you your arena points back (which requires a logout, yadda yadda).
When you log back in, post ANOTHER GM ticket, saying that you accidently deleted the item you just got the points for. Don't mention the fact that you got a refund of course, just say you accidently deleted it instead of the [Generic Item of teh SUCKZOR].
The GM will search your loot logs or whatever they call it these days, and voilá, you get it back either in the mail or traded to you.
THUS LEAVING YOU WITH 1.8K POINTS AND A FREE S3 EPIC.
I've done this twice now. Keep in mind it helps to write out the object's exact name, so for example write "Vengeful Gladiator's Felweave Handguards" instead of "my s3 gloves, lol".
TL;DR version:
1. Collect 1.8k arena points
2. Buy S3.
3. GM ticket to refund S3 item.
4. Get arena points back.
5. Log in again, post another GM ticket about item that was "DELETED"
6. Get S3 item back.
7. Profit!
It has worked twice now, so not like it's a one time thing. Also make sure you have lots of item restores remaining.
