Some of the ultimates seem just too OP while the other ones are too weak or have too hard drawbacks.

Aatrox - Very good as it boosts the entire DPS of the team. I think it's on the OP side though since Massacre doesn't have the highest of cooldowns.

Brand - The AoE thing is cool and seems very powerful in tight teamfights, but seeing as this is technically Lich's ultimate the change could've just boosted the damage, lowered the cooldown and increased the bounces and range.

Caitlyn - I think this change is actually balanced but I doubt Caitlyn would even get this item.

Cho'Gath - So Cho'gath basically has 30% more stats than another champion? What if their champion is an Aghanim's Mundo who has about 10k HP :/ Taking enemy stats isn't very wise as it's too OP..

Mundo - Unless there's a cap on the max HP, the HP this skill can get you is insane..

Draven - Hate this ultimate, only cause of the suicide mechanic.. It's terribly underpowered if it has such a horrific drawback, what if the enemy dodges his Axes? Draven auto-suicides so the bonus damage and gold gain don't even matter..

Ezreal - This was a nerf.. If you're able to deal 120% of your ult damage only if you land 3 of them for 600 mana then it's not viable..

Fiddlesticks - You're basically making him more annoying. Nothing else, but more annoying.

Gangplank - Not really the winner of the most OP one(IMO Cho Aatrox and Mundo provide better ones out of those which I have covered) The thing is, this one will be OP if you have no way to get out of the radius ASAP, but if you do have a way to dash or blink out then it won't really hurt you as much.

Hecarim - Biggest change was the range increase, this allows  for an even harder initiation and those four horsemen are just plain annoying.

Irelia - Seems fun to be able to do infinite damage and sustain off a massive creepwave for 15 seconds.

Janna - Don't mind my opinion here, anything that buffs Janna is awesome and rocks ^^

Kog'Maw - Well if you have infinite mana with AP Kog you'll start murdering people.

Lee Sin - The dota-esque refresher change isn't very good on a single target knockback nuke, this lets Lee Sin knock an enemy into his team twice making sure to kill the enemy especially after the armor shred.

Maokai - The supportive ultimate is awesome though the cap removal is pretty damn gross if your team is tanky and fight in the Maelstrom.

Teemo - Like what the hell... Why... Those static traps are already annoying :/

Wukong - The idea is cool, but the Decoy idea is easily abused. What if your Wukong is low on HP and he uses his Decoy? Then he's pretty much guaranteed to get 50% of his CD's refreshed.

Zilean - If you want such an OP ultimate and decide to increase it's mana cost to godly levels on a low mana champ then go on :P
