While in combat, as many know the BWL and AQ fights last much longer than an average 8k Mana pool, and so we must keep our mana flowing in order to keep our tanks and dps alive.

Gathering Night Dragon's Breath
There are 4 Plants scattered around Felwood, each with a 25 minute cooldown before they can be farmed again. Each farm per plant will give you 4-7 Night Dragons. In my opinion, 2000-3500 mana restoration for free is something that cannot be missed. However, plants will Despawn from time to time, and if not cleansed, must be cleansed before farming commences.
See: Cleansing Felwood http://wow.allakhazam.com/db/quest.html?wquest=4102 , for information on obtaining your Cenarion Beacon - http://wow.allakhazam.com/db/item.html?witem=11511
This works in the similar fashion to the Argent Dawn commisions. Upon collecting the various hand in's, you can return them in exchange for plant salves. These will cleanse the

Night Dragons for you. The great thing about farming these hand in's is they fall from all mobs in felwood.
This is great if you are also farming Demonic Rune; http://wow.allakhazam.com/db/item.html?witem=12662
To make the farming of Night Dragon's even easier, I suggest you download Felwood Gatherer:
http://www.curse-gaming.com/en/wow/addons-2446-1-felwoodgather.htm
This displays your cooldowns, and alerts you at 5 minute and 1 minute Intervals when the plants will spawn. You must farm the plant to begin a succesful countdown.
