Future: Summoner Spell remake!
Now this is not even confirmed or leaked or even talked about. But I know that its coming. From bland characters to more complex design, runes to more variety of choices... types of dragons, new jungle.. it is obvious to see the summoner spell changes incoming.
They will obviously want to either remake all the spells, or make completely new ones altogether. They, Riot, will say "Flash is becoming too reliable as a choice for almost every player" or "We are going to create new summoner spells that are not reliable to a type of champion or lane, but the 100% to the situation you are in". I am fine with that, but im sure it is coming.
