There are so many passive things you can already have that I don't really think this is neccesary. As anonymous #2 said:

"There is such thing, its called runes and masteries.

No need for more passives, imo."

Masteries give the qualitative passives, runes give the quantitative passives, champions give the unique passive. If there are any more passives, it would just replace the need for getting a particular situational item like mercury treads for tenacity or executioner's calling for healing reduction.

The fact that you can't find a use for your 2nd slot proves the fact that there are so many passives already. You have so much health regen, that you don't need heal. You have so much tenacity, that you don't need cleanse. The main point I see with summoner spells, is to compliment your gameplay.

If you can't find a use for your 2nd summoner slot, just ask yourself what problems you have. If you die early because of crowd control, cleanse is great for that. If you find yourself in a bad position most of the time, flash is good for that. If you find that you are wasting a lot of time walking around the map, teleport is good for that. Some of these spells may just help you early in the game and you find yourself never using it like clarity for example, but think about if you didn't have that simple early game boost, how the game would have changed entirely from your favor, to not.

tldr: There is already enough passives. If you want more, buy items from the shop.
