I'm not saying she doesn't count as a water mage, I mean she doesn't count as far what I'm looking for in water mage is concerned(if that makes sense, I'm sleepy and that sentence in general just seems off).
Like yeah she has damage, but regardless her kit is one that's dedicated for support and as I said, I'm honestly tired of water mages or the water element in general for that matter as a supportive element. It just gets old after multiple times in a row across multiple games, and I'd like to see something different for once. Like don't get me wrong, I quite like Nami but I'm pretty sure I'd have liked her more if I hadn't played countless other water themed support characters/builds/specs in other games.
