Amber Shard Farming [no downtime on mobs]

Hi all, me again. Just found one more nice location, for farming [Dread Amber Shards] + farming ore from dead mobs + a bunch of greens ... 
The place is a little island in Dread Wastes .

Location:

There is a 3-4 groups of Muckscale Shaman,Muckscale Ripper,Muckscale Slayer and they are attacking all the time Kyparite Pulverizer. And a sec after you killed any of them, new mob are spawned again - no downtime . They are dropping a lot of Dread AmberShards, bunch of green items, cloth and there is a chance of a couple of blue items too. Also you can get 3 JC recipes there: Powerful Primal Diamond - Impassive Primal Diamond - Ember Primal Diamond . 

Requirements:

• LvL 90 character
• Classes: Pala(Prot) - DK(blood) - Hunter *dont know how its gonna work on other
• Good Gear (i prefer plate for this farming)

As usual I'll make a HB profile too:
