No class in this game is hard to dps with. Maximizing dps while reacting correctly to encounter mechanics is what makes it fun/challenging. I could "maximize dps" for any class in this game on patchwerk if you gave me 5 minutes to find their rotation on a guide. There's a reason not every mage in the world can get into top 10 guilds. I don't think this reason is that every mage can do the same dps as theirs.
