An old player returns, Few questions.

Hello

I've been playing this game since early release 2008 but now i've had 3 years brake thanks to college which now finnaly is done.

I'd like to start from a clean page from lvl 1 and would like to ask current players to tell me which is the most fun champion to lvl on your opinions and why?.

Thank you,
Have a good weekend everyone
