Help with shop - Feral Druid

Hello guys, i've gathered enough coins (after farming quite an amount of gold) for buying an item from the shop, and i can't decide which. I'm feral druid, you can check my itemization atm in http://armory.warmane.com/character/...ecrown/summary

I was thinking of buying one of these:
- signet of twilight (heroic)[ http://wowwiki.wikia.com/wiki/Signet...light_(heroic) ]
- Oathbinder [ http://wowwiki.wikia.com/wiki/Oathbi...neral_(heroic) ] or
- chest t10 heroic sanctified [ http://wowwiki.wikia.com/wiki/Sancti...iment_(heroic) ]

I'm guessing the trinket would serve me best, but i think oathbinder would be the hardest to get (my guild is small, we dont run 25 heroics yet).

What do you guys think? Ty very much in advance!!

Sharpened Twilight Scale HC is probably harder to get than Oathbinder?

However, any of those two (STS Hc or Oathbinder HC) will do it for you. Oath gives plenty of stats and arp, while STS gives an imba AP proc with lots of arp. Donating for Sanctified Chest is just wrong, as your chance of getting marks is way higher than the actual STS HC.

Keep in mind that you’re probably not far from LK 25 man, and there are not too many classes that need Oathbinder there. Not big Difference between normal and HC make your decision easier -> Trinket: STS HC.

I’d pick the trinket, as it’s harder to get, and there’s no other trinket that’s very close to it for Feral, which si not the case with the weapon.
