Lemme just check if i'm doing my role as a SMN right, in dungeons and boss fights I always keep my DoTs applied to enemies and while waiting spam Ruin I. (Because I'm still level 35, so I only have Bio 2 > Miasma > Bio > Thunder > Virus [I use this on bosses or tough enemies only])

As I'm waiting for the DoTs, I spam 1 or 2 Ruin I, Aetherflow (when available to keep MP in check) and energy Drain. Is that okay?

I'm still new about pet positioning so I just put them on the side so they won't be caught by AoE.
