Red Bull "dominance" never actually happened the way people talk about it.It's been like this for decades. Williams, McLaren, Ferrari, red bull, Mercedes all had periods of dominance. At least this year it looks like there are 2 ~ 3 competitive teams. The mid field looks close too.
Football isn't any different. Every year you got the same handful of teams in the finals.
Stability in rules and aero that actually allows cars to follow and pass is what's needed.
Yes, Vettel and Red Bull won 4 championships each, but only 2 of them (each) were dominating victories and they weren't even on subsequent years:
2010 - Vettel wins by only 4 points
2011 - Dominating year - Vettel wins by 122 points
2012 - Vettel wins by only 3 points
2013 - Dominating year - Vettel wins by 155 points
Similar trend in constructors championship, 2010 & 2012 were tight, 2011 & 2013 were Red Bull dominating
