I think Pep and City's dominance will only be good for the league in terms of raising the standard of football and forcing the chasing teams to match the quality they've set this season. They've just won 15 matches on the bounce and will probably go the season unbeaten. I think this is really similar to how Wenger revolutionized player diets and implemented sport science techniques when he entered English football. Also how Mourinho reshaped the tactics or even billionaires bankrolling clubs to change the approach to a transfer window or unique players influencing tactics. Pep may influence another revolution.
