It probably makes no difference, but since i want to improve my gameplay and climb the ladder, i tought if there is any advantage to haveing one of those key set ups for summoners. What are your toughts?
(Pls no bulshti spam about this not being important, ect. )

canpan142 votesIt is just preference. Some people like it on D because there is less of a chance they will accidentally hit it. Some like it on F because it is easier/more natural to press than D.
At the end of the day it is mostly preference and what feels more comfortable. It is only going to chance the game if you forgot which one you put on which and press the wrong key.
Toxiç2 votesHonest Answer: Preference -- I use D for Flash ;).

xMercFox1 votesI have "F" for 
simply because its easier for me to press with my index finger rather than "D" with my middle finger/ I can time flashes better for escapes and flash ulti with index finger.
SmolButSas3y1 votesF FOR
Personaly f is easier to press mainly because on key boards there is an indent which makes me realize thats where f is, so then i dont miss my key
DrNova1 votesI prefer F for flash, because I find it easier to slide the pointer finger down, especially when I need to flash escape in a panic. Just much smoother.
I tried it on D, when I would have a panic moment where im suprised gank, I always messed up D flash. F is just more fluid.
And since Ignite is Usually part of a planned attack or skill rotation, the little bit more awkward finger movement is less impactful since you hae your rotation planned
NillaDooms1 votesI have flash on D because the key right above it is E which in many champion kits is a dash , Lucian graves fizz ekko for example all have dashes on E.
Xinotine1 votesF -
D -
Honestly, just whatever you are used to.
Stellafreyja1 votesI personally put on F because Flash begins with an F. I just find it easier especially since you have to switch out your other summoner spell depending on your roll.
