Newbie question on Smn dots

[Havenchild]

found it, it was located under "Character Configuration > UI Settings > HUD > Targets > Display only detrimental effects you inflict"

However doing that hides buffs on the mob also.

Another way around this is by being proactive from the start of a fight. (Also let's you visually see your DoTs)

Using Bio2 -> Bio immediately and then swiftcast a Miasma onto the target. This near guarantees you'll get all your main DoTs up at the start of the fight. After that you just make sure you never let them fall off a mob so refresh early as needed.
