Just because something is popular, doesn't mean its broken. Ignite and Exhaust are frequently used in all three lanes, are these spells overpowered? No, they simply cover the widest number of scenarios. Utilizing the other summoners is very good to strategies and specific teamcomps - they're more niche summoner picks because their utility in use is significantly lower, but open up a very interesting strategy and gameplay (see: Teleport/Revive Strats). Flash simply grants a significant amount of utility to a champion in nearly every circumstance. Its one of those summoner spells that  evens trades out when its burn, simply because that pressure of utility is gone.
