I understand the switch out, admittedly, it's just I worry when people mention the fighter as straight damage.
Counterbalanced by the people who get worried when the fighter is mentioned as anything OTHER than straight damage.

I'm also arguing that Dominate Person is in itself a gigantic source of DPR when it works and a much more powerful ability than fireball just on a conceptual level. Also, any Vancian system where the Wizard can't learn both spells and prep certain ones based on the day is kinda weird conceptually.
Sorry, I'm just used to playing PF where the standard means of playing a lowball optimization Wizard is to play an Evoker. And if they're just talking about nerfing damage from Fireball, that makes me worry they've just nearned to nerf Evocation.
I can easily visualize a charm/dominate that is balanced with the fighter in terms of usefulness, and just like the fireball gets meaner by using higher level spell resources. I wouldn't give up hope yet. Also don't forget there's only so much ground they can cover in a seminar. There's still plenty to suggest they haven't abandoned canny fighters with combat options.
