meta summoner spells
You know what grinds my gears? When I'm playing team builder and I get kicked because my summoners are not "meta". The mentality that some players have that think it's following the script that wins you games, not the skills of the people actually playing them. Not all of us steal a build online to play champs, we can have our own playing style and sometimes that means having different runes/masteries/spells/items than "meta"
