First time healing (AST) - what should I know?

[Misutoraru]

Unpopular opinion- go play conj. Start with sastasha. Get comfortable healing and dpsing in there. Move to he next dungeon. Etc. These ppl advising you to focus on healing and not dps at first are the reason why so many healers get to 60 and have no idea how to anticipate incoming damage and respond. They play reactionary. Dpsing as a healer is primarily what forces you to learn to play proactively and anticipate damage.

unfortunately running the same dungeon numerous of time will only get you better timing of the dungeon mechanics
but you could not help when queuing 3 total strangers, you will takes time to understand them, their ability, their CD timing, and their equipment
and to be honest AST only get gravity at 52, which change the dps of AST in big pull
actually those 5X leveling dungeon is a better learning environment, at least for my AST is
