I really want to play my Mage in BfA but am put off by how squishy they have historically been, is this still the same? I hate the thought of getting to 120 and finding a rare and not being able to solo it and having to wait for help, maybe I've been spoiled on my Lock where things like that aren't a concern.
How do Mages play at 120 for solo stuff (WQ's, rares etc)?
