[World of Warcraft]Gathering Herbs

I have a daily routine of farming herbs like as careing my flowers in RL :-)
Here is the list of area which is better for herb gathering.

Azshara

(Click to enlarge)

Pros - Very close from Orgrimmar, many nodes for Dreamfoil, Golden Sansam, Mountain Silersage, Sungrass, Purple Lotus.

Cons - There are so many competitor in this area. The nodes might be empty already.

Ashenvale

Pros - Very close from Orgrimmar, has Moonwell usable as horde.

Cons - There are only a few nodes at Felfire Hill for Gromsblood.

Wintersprings

Pros - Nodes of Black Lotus(rare), main area for for Icecap, and fair amount of nodes for Dreamfoil, Mountain Silversage. The lv of NPCs are higher than Azshara so less competitor here.

Cons - We'd have trouble with cats at Northern area, and Demons at the cave.
There are some eager farmer for Black Lotus.

Felwood

Pros - Can't miss this area for Gromsblood and Plaguebloom. There are some Dreamfoil too. We can gather Night Dragon's breath and Whipper Root Tuber.

Cons - Nothing but bored.

Duskwood, Scarlet Monastry, Desolace
Cons - fair amount of nodes for Grave Moss. Even in the most congested server (Blackrock) I could farm them at Duskwood. In Muradin there are no rival.
Pros - A tad far from main cities.

Blasted Land
Pros - Good for Gromsblood, Firebloom

Cons - Too far from Horde activity.

Silithus
Pros - Few nodes for Black Lotus, Fair amount of Dreamfoil, Golden Sansam.

Cons - As priest I can't manage spiders and LV60 elites sometime, so not going there other than guildies tell me BL is up.

As this list horde is easier to farm herbs than Ally I'd say. Or there are some good area in Eastern Kingdams which I don't know?
