PSA: Roots are NOT stuns
You're not completely incapable of action when you're rooted. You're free to auto-attack, use abilities/summoners (except flash), use active items, and otherwise make an impact on the game.
Whenever I see someone complain about how "Morgana's stun lasts forever" or "Lux can support too because she has a stun!" it really ticks me off. I've seen people in game who just stand there waiting to die when they get rooted, and it's so frustrating because they COULD have lived if they had just fought back.
GETTING ROOTED =/= GETTING STUNNED. STOP DISSEMINATING THIS MISINFORMATION.
