Protip: Change password and uninstall League before you leave
I've seen numerous posts about people getting their account banned after taking a long break from the game. Most claim that Riot banned for toxicity(hacked) / and third-party programs.
Just change password to improve hack prevention and uninstall so Riot won't confuse anything else with a cheating program for League.
Have fun on your days off! [slayer-pantheon-thumbs]
