Sorry to drag up an old thread, but just wanted to say that not much has changed over the years..
Miasma is still easy to farm and i can never ever fight her in her spawning area and loot before the next one spawns......
On the server i play she spawns within seconds, not even the most basic of rules will allow me to loot before she pops up again demanding to be honoured...
I just drag each one outside onto the path and loot at my pace.......
I do use the honor/lightning stike script from here which is faultless.....
