Let's assume that it is not a bug for a moment, then it means they have purposely nerfed the Mage class, who btw has **bleep** defense. So, which is it? Truly a bug OR they purposely nerfed a Mage's damage, attack?
If it's not a bug, I probably wouldn't replay the game at that point then, and I wouldn't pre-purchase the next game before I see the Mage's combat mechanic. When I played Dragon Age Inquisition, it was the FIRST time I had ever felt comfortable playing as a Mage. They normalized playing as a Mage imo in that game, as that was the only game where it was much easier to play as that class. I have tried playing Mages (or other types magic users) in many other games, and it NEVER felt right, easy or fun. But DA Inquisition? They normalized it!
I still maintain this is a bug, however. The slow, awkward mechanical "baseball windup" (as the other guy put it) is just not normal. How do you normalize something in the previous game to turn around and destroy the normalization of it in one fell swoop? This is like creating FFVII for example, and then being like, here's Legend of Dragoon. My friend called that game as Poor Man's Version of FF VII.
I mean, you literally have like a natural, progressive, 6 movements motion attack as a mage in DA Inquisition. But then in The Veilguard, it's a SINGLE awkward af attack which makes no sense. What type of person would use a staff that way??? That just can't be right. I don't think anyone playing as a mage paid X amount of money to play as a mage, only to have a main attack that people consider a bug.
