In case some players didn't noticed yet there are some small click-able coups/bottles on the "Isle of Thunder" around "Zandalari" zone ( south close to "Zatual").
They provide really nice 1 min buffs
Jaguar Ferocity: increases damage by 25%.
Jaguar Speed : running speed by 75%. (tried mounted too but it don't speed up the char)
Jaguar Stalker: go stealth mode and guarantees a critical hit on the next attack (this also seems nice for PvP lol)
Tried to stack these buffs but apparently you can't drink another bottle till the 60 seconds previous effect ends
I recommend to farm Prince rep in this zone (if you don't have a better spot yet) since is very easy to see and drink these potions and you will kill the mobs much fasterAlso keep in mind that neutral mobs in this zone also are giving +rep (lower than enemies tho)
Additionally during your kills you can also kill the big "Drakarri God Hulk" trolls, not only they give 55 rep each but they also give another extra buff called "Mighty Loa" witch inflict additional damage to the mobs.
So have fun farming prince rep with more dps buffs on you ^^
Also nice to look for all these buffs even if you are there just for the daily quests in that area.
Edit: Before you move in this zone (or any preferred zone by you) to farm rep keep in mind we are still in Darkmooon Festival period and you can take the "The buff is named "WHEE!" witch increases experience and reputation gains by 10%" by simply staying on the carousel at Darkmoon Faire for few seconds (buff stacks every few seconds till 60 minute)
Also you can farm "Darkmoon Top Hat" doing the daily quests on "Darkmoon Island" and they have a chance to drop inside "Darkmoon Game Prize" witch you can carry with you and every use will give you +10 % rep for one hour (+ a funny hat view on your head).
"Whee" buff will not stack with the hat buff tho (even if you can see both of them will still be only +10 % rep).
