If You Could Buff Any Champion You Wanted Without Restrictions...
Basically this is a sort of challenge where. 1. You Apply a buff to any champion in the game. 2. You have no restrictions outside of the fact the changes must be an overall buff
This isn't quite a "Come up with crazy ideas that would never fly" that would fit more so in concepts. I was thinking of more serious buffs. A few examples I thought up of like...
W(Living Shadow)
Living shadow will now auto attack any nearby monster that is neither a pet or epic monster. (So excludes things like Tibbers and Baron)
in conjunction with Zed. (So if your trying to fight say... Blue Buff, and you drop your W next to it, and both you and your shadow are in AA range. When you auto attack blue, the shadow does as well.) Each auto attack the shadow makes reduces Living Shadow's cooldown by 1.5 seconds, and restores 10 energy.
I actually really like jungle zed, it's only saving grace is respectable ganks. However due to the horse shit clear that is to be expected it just sucks. So a buff on the W to make it help clear camps. I doubt this would make Zed Kha'six level clear though, due to the fact that his base attack speed is pretty shitty.
R(Demonic Ascension)
Demonic Ascension can now be cast with zero soul fragments. but demonflare will not trigger with zero fragments.
(Unless I'm mistaken, Swain actually has complete dominion over the demon of secrets. Thusly he should be able to transform without soul fragments. However if he uses them as a sort of fuel for the demonflare, I could see why having none would prevent him from using it. He doesn't lose any fragments upon casting so I thought this change would make sense and be neat gameplay and story integration.)
Q(Infected Cleaver)
Infected Cleaver will now apply a debuff that causes the next cleaver to deal 3% more, but increase the health cost by 1%. Stacks infinitely, and will be consumed at no benefit/loss upon taking damage from Burning Agony.
(It's called infected cleaver, but I don't see very much infection about it.)
Well hope you enjoyed, I hope you can post some more interesting ideas for buffs in the comments below.
W:
Forces your jungler to path over your W when they are nearby with missing health, so your Bard doesn't feel like an idiot for trying to help his jungler and skilling W first and then being forced to waste those jungle shrines SINCE YOU CAN ONLY HAVE THREE, ALL WHILE YOUR JUNGLER IS DRINKING ALL HIS HEALTH POTIONS LIKE HE'S BEEN TRAVELING THROUGH THE ENTIRETY OF SHURIMA ON FOOT WITHOUT WATER SUPPLIES ONLY TO REALIZE HE LEFT THE OVEN ON AND WALK ALL THE WAY BACK.
Plus 5 Base Movement speed
every hook hit is an instant kill and adds a powerful soul that's worth 10 regular souls
R:
QWER:
All abilities can damage structures. Ziggs can truly terrorize the rift with this.
Q - reduced mana cost, self-heal removed
W - health cost removed, CD increased, soraka can self-heal with it, now grants 16 armor and MR per rank to the healed ally for 2 seconds.
E - reverted to pre-rework state
R - now brings dead allies back to life in addition to other effects, their HP is what her ult heals for.

passive from Love Tap to Claim Bounty. if she gets an assist on a shut down she gets full bounty as if she got the kill. (she is a bounty hunter after all)
clip size based on his level.
lvl 1= 1 shell
lvl 2= 2 shells
etc.
and to balance it the larger the clip the longer it takes to reload. so 1 shell takes half a second and a full 18 shells takes 9 seconds. and every 100% atk spd buff cuts the reload time by 50%.
hurricane can be used instantly at the same ratio as max charge
shield toggle and drain mana for every damage it takes at 66% reduced expense (hit does 100 dmg instead of draining 100mana drains 33mana)after armor reductions
W: stack with ad and ap
E: triggers W
R: stealth per Q duration 1/1.5/2s time spent in stealth doesnt waste R timer. R refresh entirely per champs kill.
(nerf) Revert her.
kills a unit with Requiem you may activate it again in a short period of time, however the cost is increased to 150% of the previous cast
100/150/225/348 and so on
Passive:
Whenever a leg is proc'd, a clip of Bricky saying Shotgun knees can be heard by nearby players.
Nothing foo insane. Just fix all his bugs. >.<
