Yeah, Flash is a horrible spell and 90% of its uses are just anti-fun. Set up a good gank as a jungler? Nope, they flashed. Got away from the enemy with skillful jukes? Nope, they flashed in for a last-hit. Coordinated a pincer attack with your team in one of the jungle corridors? Nope, flashed over the wall.

It's broken as hell at the moment and everyone taking it is incredibly annoying. I mean hell, when was the last time you saw an Ezreal not take Flash even though his E is a better version of Flash on a lower cooldown? (Incidentally that's the same reason Ezreal is a cheap annoying fuckface, but I digress). Flash really needs some kind of rework, either being replaced with an item so the people/champs that can actually make good plays with it can still access it, or being changed in how it works somehow so it's not just a "get out of fail free" card that everyone has to take forever and always. And it frees up a spell slot - at the moment the summoner options are usually "flash and something else" whereas now they'd have the option for whichever spell they were going for before, and hey, maybe even Clairvoyance! So yeah, more variety in summoner spells can be achieved just by making Flash less ubiquitous.
