I don't miasma 2 except for my opener, only use shadowflare on opener and before DN come out. I only bane DN, don't fester them, the longer they're up the longer my dots tick on them the more dps I get. Ruin 2 as little as possible, I try to use bio recasts to weave my festers. RS+int pot at the start, on the 2nd DN, and then when its up again with another int pot (we don't get any more DN after the 2nd one). I ask for about 10-15 sec of foe, just enough so I don't need to energy drain.
