Season 1 and 2 was the most fun I ever had in league. All the champs released during those times were my favorite - Akali, Ahri, Lux, Irelia, Diana, Caitlin, Ezreal, Miss Fortune, LeBlanc, Jayce, Jarvan, Orianna, Brand, Vayne, Wukong, Riven, Elise, Syndra, Zyra
Season 3 and 4: Lucian and Jinx. ROCKETS AND LASERS PEWPEW I GOTCHU
I don't play much now besides an aram every month or so. Sadly, I got bored of league
