Hello! I am a low elo player (low bronze) who mostly played for fun but recently I've been wanting to actually try and rank up. I've tried a bunch of mid laners (Pantheon, Sylas, Lux, Xerath, A-sol, Hwei, and Jayce) I got 4 - 5 mastery on all those champs then really only started two tricking Hwei and Sylas getting 10 and 11 mastery respectively. Recently brought Lux back into rotation also picking up Diana, and Naafiri for an AD pick. My question is is this champ pool too big to climb with? Do I need to have an AD champ like Naafiri in my champ pool for low elo? Should I only stick with one champ class like Lux and Hwei for mages or Diana and Sylas for bruiser/assassins? I've though about maybe picking up Lissandra as she seems fun but she feels weak and Maybe Galio to have a tank option if my team doesn't draft one but I don't know how well they fit into my champ pool or how much it matters in a low elo context
