[2] The Guild are big on people on like to sit down and write a lot.But being a wizard requires you to sit down and read a lot, and often sacrifice any kind of social life for the sake of better magic.And if you base it off things like Fate Zero... Your potential to be a wizard is mainly dependent off your blood. So you can genetically be a horrible or great wizard.
I'd happily sacrifice my social life in researching the dark arts, immortality, plague spells etc.
Being a mage/wizard would be dope as fuck.
Thieves can suck my fat staff.
