Reason for my top choices
HOW COULD YOU NOT LIKE THIS CUDDLY BALL OF FLUFF?!
Pirate... Need I say more?
Reason for mid choices:
HE IS EVIL STOP LAUGHING!
Lazer ult that melts... Yep.
Gloroius evolution!
Explosions first, questions later.
Voidling army with 40% CDR and that ult suppression.
Reason for bot lane carries:
She is crazy.
Machine gun arrow autos...
That range.
Sewer skewers and ambushing your own lane!
That shotgun.
Reasons for supports:
She was my first support. Plus DJ!
Just try to get my carry, or we just all in you.
That bind with Tormented Soil... Yikes.
Reaper skin and HEALS FOR DAYS! Unless I'm low on health.
The junglers are just fun for me. Thats all.
Because 
syndra cause you get to throw frogs and random stuff
**Against squishies: **Q, E, R, E.
With cdr: R-ing minions because your ult's going to be back in what, 30 seconds? Miss your ult? (which I do, frequently) Isn't too bad, because you don't have to wait a couple minutes to use it again.
When you're escaping: hope no cc comes your way, run till your Q is up, land your Q and you're safe. If you didn't land your Q, E and sometimes you'll still get out.
I stole a dragon with my ult too :D
Yasuo, because mobility. Seriously, I love extremely mobile AD champions that do insane damage, and are actually useful in teamfights.
but I like mobility and damage over usefulness. that's why I like playing zed too.
