Cool quality of life option
What if there was an option that when checked, you cast your abilities at the max range from where you are standing, instead of making the champion walk into range and then cast the ability?
Seems kind of like a useless option at first glance, but when you are playing a champion with a ranged aoe ability (like Annie R, Soraka Q, Xerath W), buffering that ability would be super smooth. You could compare R buffer into flash on Kassadin (his R has this functionality already where his R already tries to go max range when you target it outside of the range, similar to flash) to R buffer into flash on Annie. And while you can do the buffer on Annie already, you sometimes get stuck in this awkward position when you are slightly out of range of ulting after you flash where you just stand there like an idiot when you would prefer if the ability was just cast anyway at max range (try it for yourself in practice tool).
Just a nice little quality of life option for those who want it, let me know what you think.
