@Riot, if you REALLY want to see diversity in summoner spells...

... then rework this aspect of the game entirely, instead of forcing a single spell at a time along with into the meta and alterning it whenever you change opinion.

The summoner spells system is amongst the oldest thing that are still in the game, along with (until its recent rework) the old cursor. Masteries got changed. Runes got changed. The honor system changed. The game interface changed. Almost the entirety of the item pool got changed. The champion roster pretty much doubled in number. And yet, the summoner spells are still the same. Worst; it only got downgraded with time, unnecessarily buffing and nerfing some spells or simply just deleting some of them like Revive, Clairvoyance of Clarity who got removed from Summoners Rift.

If we exclude , there are 8 usable summoner spells in SR, and since is a must in almost every single situations, we go down to 7 actual different choices. And since the balance team seems to decide which spell should be good and which one should be very bad, actual freedom of choice in our spells is just a myth at this point.

The current summoner spell system is old and outdated, it isn't fun to choose from the scarce options we have and its even worse when we actually use them, since everything seems dull and rusty. It is hardly balanceable from what we can see from the balance team's actions and has stopped to be interesting years ago, to the point its not even a decent feature of the game anymore; it became a stain that everyone sees everyday but ignore it since it has been there for so long it kinda became like its part of the background.

TLDR: Summoner spells shouldn't stay a serious balance topic anymore, they are outdated and should be entirely reworked or even completely removed to be replaced with a more efficient and interesting feature
