Suggest one small change to a champion that'd make them quite overpowered.

Zed and his shadows now laugh and spawn Mastery 5 icons upon killing an enemy champ.

Remove cap on garen's W, now scale infinetely

's clone now moves and uses basic attacks.

's Q lets him ignore ALL collision while he's on it. Including walls

gets a real weapon

Mordekaiser gains the full benefit from spell vamp as opposed to only one third.

On second thought... That may be a cool addition to his passive to give him an incentive to build some sustain^^

Ult has no warning and no channel time.

Double-Up continues to bounce until there are no enemies behind the last target Ult no longer has a channel time :^)

Make Q stack AD like Q

R ignores terrain.

Increase blitzcrank ' s ulti silence by 1.5 seconds

Make Thresh's q a "point and click" ability

Kindred ' s ulti only works on her and her allies

Shorten each of Yorick ' s cool downs by half

No one can move inside of Nunu ' s ulti

Nautilus' anchor pierces through enemies it hits. Anyone that ends up getting hit by the anchor bunches up, and nautilus pulls them all towards the first person he hit. If his anchor connects with a structure and enemy, he pulls himself and the enemy to the wall, stunning them for 2 seconds

Shorten Yasuo ' s windfall cool down by 5 seconds

Braum ' s passive has no cooldown (This is really brutal)

Caitlyn's ulti pierces enemies that try to block it

Lux gets a global laugh

Every Q is a tornado that knocks up, not just the third

Caitlyn saying "Boom. Headshot." every time she attack with passive.

kassadin's R doesnt have a scaling mana cost :^)

Ult refreshes on kills

Q slows all units hit.

the clone actually chases people correctly even when you die, or the boxes don't cause people to run away in fear. the w debuffs attack speed or heals you q has an execute function e had a cast time of .25 sec or less chalice is a viable item w works on itself q can kill your own minions e is a passive dodge and stuns when a dodge occurs w does damage when people pass through it w is homing

Sion (R)- Unstoppable Onslaught.
