So I did expert on SMN (main job) and I had an AST drown me in Spear cards. It was amazing, and I feel like it's "our" Arrow card, using it with all of my cooldowns for burst, only to have that burst and associated cooldowns come up super fast (fast fester, too, felt odd and amazing). I used to think Ewer was my favorite card, but Spear is really an awesome card and making Aetherflow come up faster feels like a pseudo-Ewer. I wonder how it compares to Balance as an overall DPS increase for single target.
