Flying Lizards got you down? No worries! If He flies next to a wall hit Him with a slow shot. It should make Drogoz fall due to the drop in speed. Try to bait out a Salvo and Weightless out of the way. Making Him waste an ability and need to reload.
If you find IO while Luna is still active, instead of targeting Luna to get her down go for IO. When she dies, her fox dies. This is similar to Barik with his deployable and Inara with warder's field. They all are removed from the field after death
As a support, be wary of Dead Zone! Do not stand inside it unless it's unavoidable and do not attempt to use healing abilities on allies affected by it until they've been cleansed. Remember that the effect lasts for 2 seconds after exiting.
