@ RoznosicielCiast: how can Ghost help me catch someone that flashed over a wall? How can it help me catch Riven who flashes, dashes with Valor AND with Broken Wings? If you don't have another mean of improving your mobility or something like a perma slow (like Trundle's Chomp) Ghost won't be enough, 8 times out of 10, to catch someone with flash.

Exhaust doesn't solve the problem either. 2.5 seconds of 30% reduced movement speed but, you know, you also have to cast it on yout opponent. What if he flashes before you exhaust him? Lol.

Not to mention that both Ghost and Exhaust have a cooldown of 210 seconds, only 90 less than Flash. Not that much.

Finally, you've never heard about other summoner spells being overpowered because... maybe... they aren't! Ignite is an offesive only spell, Flash can be used defensively too. Exhaust only lasts for 2.5 seconds and it does nothing to ap based champions. Teleport has the same cooldown of Flash, a 4 seconds channel windup, can be easily predicted by opponents and does nothing in direct combat. Barrier is a defensive only spell, while Flash... you already know this.

Is it a little clearer the reason why lots of players consider Flash overpowered? It simply offers unmatched utility, can be used in a hundred ways and it is practically uncounterable but with another Flash.
