I don't agree nor disagree tbh, all we've seen is a trailer. I loved quake as well but the people commenting on it have nearly no idea on how impactive the class system is, the devs have said it's incredibly minor so we have to wait and see some gameplay really.
Overwatch actually has shown that you don't need to compete with other big fps games, just be different enough to sit in your own space. TF2 held that space for an extremely long time as it decayed and Overwatch just took over as they flat out decided they didn't want to compete with CSGO.
I don't think id have that creativity in their ranks at the moment though. It sounds like they're closing in on better dev quality with DOOM's single player but they've shown they still can't put out a fully fledged titan of a game.
