I would change his Windwall to have a delay, but last 4-5 seconds longer. I want to say ''FACE THE WIND'' and just stand there for a while. :P
I'd put him back where he belongs, a Solo lane. We all know who I'm talking about...
khazix getting dmg reduction on ult plz
You can cutthroat to ally units
his ult should add a stack (or two) to his passive
I would take nerfs on all his other skills for this
for his W. The first ally to make contact with the lantern is automatically going to take the lantern ride.
The fact that he sucks 
Should gain a % health true damage spell scaling with bonus attack damage and it can only be used when Q, E, and R are up because W is the button you need to press to open up a minigame where you need to try to kill as many people as possible before the nexus explodes and if you win you can use the spell. It has a 69 sec cooldown only if you are in the fountain because this promotes map awareness and control.
Better Ultimate visuals
I would make the League's premier healer stop sustaining herself through vampirism. Her post-rework kit is more sadomasochistic than Dr. Mundo's!
Solar Flare: Solar Flare is now global
BECAUSE THE SUN IS EVERYWHERE DAMN IT
free cost on W
ult renamed to "RAISE YOUR DONGER!!!"
Anivia wall now stops dashes
She is now the answer to the mobility creep
In return Q would lose its slow on pass through and only apply it with the stun detonation
Undo Soraka rework.
Give him a Harrowing skin. Bard could have a pumpkin head, and his meeps could beg for mercy before Bard throws them headlong into the enemy thornmail.
give him a passive
Loses his minimap.
W invisibility should be 5 seconds but he can't cast abilities while under invisibility, meaning you have to autoattack to get out of it. And his clone should be able to autoattack for a duration of 3 seconds benefiting from on hit effects and crits, limited to move in a certain radius, like 500 range. And his clone needs to show buffs. And for the movement animation between his clone and his real self to not twitch and glitch when he uses the ability.
EDIT: 
I would change the weird fish boobs
Hmm, I think most of his kit works pretty nicely- I do wish I had a sure way to see how far my visions can bounce.
