I started playing League of Legends as a Marksman, but then I got bored of it pretty quickly (not to deter you from playing them! They're still a big part of carrying your team to victory). Right now, I enjoy playing support and middle lane mainly because I know how A.D.C. (Attack Damage Carry / Marksman).
My top used champions for each roles are:
ADC (Attack Damage Carry / Marksman)-
○ Jinx (Hyper insane, and intensely fun kit)
○ Vayne (Hyper carry late game when fed and/or you know how her mechanics work. Mechanics for Vayne is important)
○ Ashe (Global Stun ultimate, and who doesn't want infinite slows 8D)
Support (Supports the ADC, so the ADC can support the team..?)-
○ Leona (Stuns are one of the most powerful CC's (Crowd Controls; fear, stun, slow, blind, etc.) and Leona can be "game-changingly" fun, in terms of stuns and slows)
○ Thresh (Similar to Leona, Thresh has stuns, slows and a unique life-saving lantern.. Literally life-saving!)
○ Soraka (HEALS! <3)
Middle Lane (Usually APC (Ability Power Carry / Mage)-
○ Le Blanc (One of the most known nuke mages, where she can insta-delete many champions (most likely other carries))
○ Katarina (A mana-less champion, and has a fun kit. Easy to get a Pentakill with (Double, Triple, Quadra, PENTAKILL)
○ Veigar (An annoying voiced champion, but still a fun champion. Stun enemies + Nuking abilities + Free AP with Q)
I just felt like typing this, whilst my Technic packs are downloading. These are my opinions, I'd like to hear others :3
