Welcome home bro

second, play how you like.
Chances are if you're in this clan you have the ability to play very well without playing like a nub but for everyday playing, play however is fun for you, just try and be respectful in your attitude
Having clan rules for how you play is pretty meh, clans need to be a fun place to be, the more restrictions you have, the less fun people have :P

Also apparently there's a war now or something
