well either they should remove fel flame's ability to snapshot(afaik this is how dk's festering strike works, not sure tho but it would prolly be deemed too powerful as we could potentially roll our supercharged dots with 100% crit, 100%+ haste and 50K+ sp dots the entire fight) and then increase its dmg or remove its ability to extend dot's duration completely and then increase its dmg(a glyph that did this would really help) as that is the only real way to make fel flame worth using while moving atleast for afflic, demo doesnt have this problem and destro have it to a much lesser extend due to the fact that their immolate does a much smaller fraction of destro's dps than UA, Corr or Agony does for afflic(not sure about corr tho) and as long as its like that, fel flame would be pointless to use in most situations where you need to move as afflic, usually making it better not to do anything and having haunt being castable while moving is just utterly useless coz we'll still need to MG the full duration for it to be beneficial for us, not to mention that it costs a shard that we might not have available at the time, so that is something that needs to be addressed as well.
