Fun, potentially helpful idea for you and Riot
Consider one of your favorite champs that isn't super strong or for a challenge pick someone not very popular
Now take that champion and by TWEAKING a number or two or adding a small thing to an ability make them better.
For example, I adore Nami. I propose something like Aqua Prison (Q) dealing 75/130/185/240/295 (+50% Ability Power) -> 70/120/170/235/275 (+30% Ability Power) 60 mana -> 50 mana Stun for 1.5 -> Stun for 2.0 Seconds
Her utility is where it's at. Why does this q do so much damage? But longer stun helps her be a little more relavent and doesn't cost so much later when her W is high mana cost
Or like what Riot did with twitch's cask, adding the fact that it will add poison ticks longer people are in it instead of a flat 2 stacks.
Context: I'm tired of the what's known as the Circle of the Month. We go in circle. This is strong, nerf the crap out of it without changing anything else...then there's something else really strong now, nerf that, change something else nerf that...repeat etc etc etc
So a fun thoughtful idea to maybe help Riot get some ideas how to just tweak a few champions easily without having to full blown rework them.
As always with something like this, i freely give my idea to Riot if they should decide to use it
