i was actually hoping this preseason wed finally get a summoner spell overhaul.
i think
should get split up in to multiple different item actives and summoners, so its not one summoner spell that does everything.
the aggressive playmaking option it provides should be replaced by something like 
the defensive utility could be replaced by item actives that can grant you some sort of escape. like a backwards dash or something similar
the utility portion to be able to get over walls could be replaced by 
its true that the game is currently balanced around literally everyone picking flash. but that doesnt mean the tools that flash provides couldnt be replaced by other means, without having everything in one ability.
it would be cool if summoner spells could be more flexible and not everyone would be locked into flash every game.
