Soraka
Nidalee or
Lux

-Soraka is squishy at first but with full support build she can carry teams mid with her global heal and W heal
-Nidalee throws nukes with her spear although she's been nerfed and cougar form is so good early/mid game
-Lux's stuns and her ult, the laser is just too op with an AP/cooldown build

I like Aatrox and Tryndamere.

Aatrox's passive becomes a realm live-saver and It has helped me get a few kills whilst being on really low hp. Same with his ultimate.

Tryndamere is my best friend, I've played so many games with him and hes easily one of my favorite champions. Bloodlust comes in handy to stay in lane a lot longer. His ultimate is amazing as well, 5 seconds when you can't take damage. Bit OP. He can also get out of sticky situations with his spin which has come in handy quite a few times.
His passive for crit is also a big bonus, I get my rage to full and just completely desecrate the enemy champions if it's a 1v1 due to my crit.

I like Lissandra, Syndra, Zed and Fizz. I am a midlaner and I like playing champions that have a high skill cap. I find it more rewarding when I pick up and triple or quadra kill. Although Zed isn't really made for multi-kills because he's an AD assasin. -Aquarium

Volibear! He's such a tank i love it.

Rengar, very strong and if you pick up an advantage its hard for even their jungler to help without being in a dangerous situation. He is also not seen much towards lower levels so stomping everyone I face in lane and having them complain in all chat is kinda amusing. Most people complain that he is broken(which he is), but im able to beat them without using broken aspects like lvl 2 triple q.Whether he is built tanky or ad focused, very strong and relatively easy to carry with as long as your team hasn't completely given the game up.

JAYCE I remember when he was broken, I got my first pentakill with that MOFO

My favourite champion is by far Lee Sin.

One of the stronger junglers, he can easily switch between ganking-killing 'mode' by stacking lots of lifesteal with his W's secondary active or stay as a tank/initiator.

I think the main reason I enjoy playing him is because he requires more effort put in to do well. I also play ADC quite a lot in my pre-made teams so sitting there with Caitlyn, or whoever, just AA the minions, getting creep score and poking enemies is boring.
Lee Sin is a more active, enjoyable playstyle for me.

Favorite champion is akali. Shes a quick burster and can get in and get the adc and then drop your w to get focus off of you
