played s2 and s3. Would consider myself versatile, I've "mained" (played one champ constantly for weeks/months) way too many champions and played everything there is. So never really been the guy that goes "top/mid/adc or I feed". When I still played, I tried to always switch up what I played since the game simply lasted longer that way for me. 5v5 was fun but 3v3 is just omg. Especially when me & my cousin went duo, shorter, faster, and more intense games.
The longest champion I mained, and my first one, was Riven. She was the most fun, still is today. I started out top with her, but soon realized (that at the time) she was a little too powerful and could be played bot & mid too. After doing mid with Riven for quite a while I started playing AP champs mid like LeBLanc and Lulu. LeBlanc probably comes in second at amount of time spent playing with her.
I really enjoy mid & top, I feel like games are pretty easy to carry even if your team sucks if you get a good start either top or mid (when solo). Although if I'm playing with my cousin (rarely duo with anyone else) we can sometimes go bot (mostly support for my part, Lulu or Nunu) and just carry it from there pretty strongly. I'd like to say that top & mid are my favorites, while AD carry and jungle are least favorite roles.
Can't really tell what my highest ranking would be since I shared my account a few times, but legit I'd be highest at maybe plat III or IV. Although boosted I got to play a few promotional games that could have taken me to diamond, sure it wasn't entirely legit but I was still proud... sort of.
