Flash should be up more often on melee than ranged.
I've been beating my head against the increased mobility and kiting that exists in League since season 1. When playing a lockdown type of champ, champs like Riven, Yasuo, Kalista, fast moving champs, and even adcs with mobility now, makes it very very difficult to punish bad positioning. For instance, if you are a melee champ against Teemo or any ranged champ, the range champ will always have the starting advantage as long as their flash is up. The non ranged champ, most of the time, has to spend a flash to either make the enemy spend flash or secure some kind of pick. To put it in a better perspective: melee only has a flash to spend. Range champion has both range and a flash, giving them far more room for positioning and resources. The melee champ still has to cross a distance to get to the champ, and that gives the ranged champion both time and space to do whatever they want, something a melee champ can never do.
In Dota, the balance to this is that playmakers can buy the Blink Dagger. The Blink Dagger has no stats. All it does is let you blink after a short cooldown, as long as you're not in combat. This makes it so playmakers melees can always have a way to engage after bad positioned ranged champs, or to do a surprise engage across a distance they normally cannot travel. In league, everyone has flash. As a result, ranged champs will always have the advantage in terms of controlling the space and dictating fights. So if an Alistar flashes into a team, all the enemy has to do is flash or manuever away, and all Alistar becomes is a sitting duck. His role is over, while the enemy team gets to throw damage at him cause they have the superior control of space.
This breaks the game, and is also why currently ranged champs are dominating in all roles. Jungle is an exception, but not by much with how easy it is to survive in jungle with ranged champs now (kindred, graves examples).
Flash needs to be adjusted so that it's either up more often on melee champs, or ranged champs are punished for using it. We always had ranged exceptions to many items and spells because ranged always come with an inherent advantage. We nerfed them on usage of Grasp, Klepto, barred them from using tiamat. It is now time to do the big balance chance, and nerf their mobility OR buff melee flash usage. Now that Kennen in lane can't be so gutsy knowing that the Renekton has a much lower cd of a flash, allowing counterplay. And we fix a lot of ranged vs melee problems that have existed since the start of this game.
