The only energy champion I have fun against is Shen, honestly, and that is if I am tanky as well, feels so romantic to have us auto'ing each other in the top lane, dealing little to no damage to each other, just as the seconds pass by, without any jungler or team to annoy us. I feel guilty whenever I kite a tank, and Shen is one of my favorite when it comes to personality.
I would have fun against Kennen if I fought him mid, but that guy goes top and tries to kite me, but that's my champion's problem, not his kit.
Lee... Well... Yeah, I have him, he isn't half as hard as his mains will have you believe. Asides from your ultimate and energy restoration passive, there is hardly anything to his kit to make it extraordinary or difficult to play. But man I feel like punching my screen when that 12 year old LCS wannabe Lee Sin escapes and then speaks in all-chat: not even close bby. Plus having him every game doesn't help his cause at all.
Akali is plain boring to go against. Always the same strategy, same build, same ganks, same shroud, same BS sustain, feast or famine. I hate her both on my team and on the enemy team, and her players are no better.
Then we have Zed, that one champion that once 1-shot me as a 1600 HP left Singed with at least 140+ MR and armor from my ult, just because of LW and BotRK. Super annoying laugh, super cheese escapes, super cheeky players that always bring out that old excuse: Buy Zhonya's or QSS or GA, forget about your mana issues while Zed can go full penetration on his first item! Then his players are very similar to Lee's. They are Korean wannabes that play what the LCS overlords tell them to, usually overconfident, whose shift key is already too greasy due to their furious all-chat raging whenever they get killed in a 1v5, thanks to the chips they eat while they last hit with his superb waveclear. And some of them even say he is the healthiest assassin... Run away, he has a larger blink to escape, not to mention how many abilities he can dodge with one basic ability.
Now onto the others...
Gnar is a total pain. A ranged tank that can kite, tf, push and deal %HP magic (How easy to itemize against him, right?) damage astonishingly fast. And he never shuts up. I don't have any problem with his players so far, but that kit is, to say the least, overloaded. And the hop, what once looked cute and awesome, is now the most annoying skill ever.
Yasuo is only half of what I hate. I hate more those premades that pick Malph, Ali, Cho and then feel super pro when their knockups help Yasuo get his low CD ultimate on a few of the enemies. /all rekt xDXDXDXD /all teamwork OP XDXDXDXD. But yeah, ganking someone that knows how to play this guy is a nightmare. He will dash everywhere, knock someone up, and he might even kill the mid laner 2v1. And the mains even say he is super weak, either due to his winrate, or due to his previous nerfs that changed his base stats instead of his kit. Were he that weak, they wouldn't pick him, or else he would be unplayable like Volibear in a ranged meta like this one. Luckily, the bad Yasuos still outplay themselves and are sometimes quite easy to bring down.
Then Rek'Sai... Meh, haven't faced many yet, except that AP one that killed our mid over and over again, but the player remained silent, so I have little to say about her or her players.
Then we have Riven. Oh you... 44/0/23, kills a 4/3/4 Urgot "Haha, outplayed
