My Champion.

Hello, so I've been waiting to start ranked but I don't have a champion that I'm comfortable with or really enjoy, or have confidence in. So I was hoping you guys could help me find that one. Role doesn't really matter to me either. I'm looking for someone that can carry a game wether that is through kda or assisting in kills, someone who deals lots of damage both over time and in burst, and someone who is kinda tanky but more of a damage dealer, almost an off tank. I like all roles but I'm not a huge fan of top and adc. Someone who can be played in multiple roles is nice so you can play them more often too. Also a champion that is strong when ahead but not completely useless when they are behind. For laning phase playing just passive and just farming up to ramp up for late game is nice or I like aggressive action packed lanes. Once I have a champion, I need some tips on how to spam them and learn them without getting bored or losing confidence after a bad game. Thanks in advanced.

P.S. Not blitzcrank
