[HYPOTHESIS] How much would gameplay balance be thrown off if Flash were built-in like Recall?
Flash already has around a 98% pick rate among the Summoner Spells, even though some Champions like Hecarim might go without it. It basically leads to little-to-no variety in terms of Summoner Spell picks.
Now, humor me for a moment, but what if Flash were suddenly changed to be built-in for everyone like Recall?
Would this make the game unbalanceable, or could it lead to more interesting gameplay? Being able to take Heal and Cleanse as a carry would certainly be useful.
EDIT: Also, food for thought - What if Exhaust prevented you from using Flash?
