You mentioned that you may try to get the Vengeful shield with arena points. I'm pretty sure that the s3 shields still have a rating requirement of 1800 on them, same as s3 weapons. I've just hit 70 on my shamans as well, and right now I have 4/5 of the blue pvp gear (haven't got flying mounts to do Mech yet). The SSO dailys bring in a ton of cash every day, so it might be a good idea to hit exalted to get that shield and spend honor on other slots that can't be easily filled.
