OK so I checked the neck heal for cooldowns and it looks like its the necklace itself and not the class. On my rogue his Eternal Will of the Martyr heal doesn't trigger a cooldown on health pots (what I'm calling Cooldown A) but when I created a Eternal Horizon Choker that heal did trigger the cooldown. The Eternal Woven Ivory and the Necklace Eternal Talisman of Evasion also triggered the cooldown. Can someone check the Eternal Amulet of the Redeemed (INT/STAM/SPIRIT) and Eternal Emberfury Talisman (STR/STAM/CRIT)? I don't have those. So far it looks like it's just a bug for the Agility DPS necklace not to share a cooldown with health pots.
Working on it right now, will test the Necks on all 6 Classes I have and edit this post, will take a while with the 2min per CD.
**EDIT: It's already appearing like a glitch with ONLY 1 Neck, Will of the Martyr... On a side note, the BoA Necks will fit in the 36 Slot Lure Master Tackle Box lol. Another side note, Drums of Rage are placed on CD if you use ANY of the Engineer Bombs/Dynamite.

As soon as I can figure them all out I'll post them here. There are Food Buff changes coming in 7.0, at least to the effect that ALL Food that offers +Spirit for 15m will instead offer +Versa (at a higher value than the DMF Food, since they're only 1% static). That means the new BiS Food will likely be the +4 Stam +4 Versa for 15m (various ones).
