No, this is most certainly a problem; I first noticed this on Machinist in Void ark, where I'd place my wildfire (obviously there being a visual limit I don't expect to see the wildfire) However, the problem here being that my wildfire damage will neither appear on my screen and it will not make its trademark beeping sound, which leads me to believe that it was dropped in favour of other buffs; furthermore, while this has happened only a handful of times,the majority of times I've noticed It has been with DoT/Debuff heavy teams, (Lots of SMN's, BRD's, NIN). If someone has any information that might shed light on this matter feel free to share
