Clarity [The Summoner Spell]
Here is my idea to try to help out Clarity and get the cobwebs and dust off this spell- add a passive granting 1% increase mana regen for every 1% mana you are missing (identical passive to Veigar and Chalice, which can stack with either passive). Besides trying to get Clarity to be a viable choice of summoner spell, I just think this may open up more mana reliant champions to get played (hello Anivia and Swain) and possibly Urgot granting him a chalice passive and on-demand grail passive with the active, plus the 40% mana back goes well with Tear items like Archangel and Manamune- or make whole new builds without having to build a mana sustain item.
tl;dr: hoping to open up more champions to get played and more builds to get used with adding a regen passive to clarity
or
will NEVER be an attractive idea if Clarity keeps its identity as a mana regen summoner. Those items build in to things that are still very useful as they scale through the game. Clarity loses it's purpose after 7 minutes of gameplay.
