My middle finger curl outside which means my left middle finder perfectly follows the path from S to W which is important as a gamer. Honestly, I think I'm the latest in an evolutionary arms race to produce more biologically effective keyboard gamers.
unless you have the most fucked up middle finger that shouldn't be an issue. fun fact, I moved w and s one down. s is where x was and w is where s was. makes gaming a lot nicer.
