B2 lf laid back, friendly team.

I have been playing for quite some time now, only bronze 2 because I do not have the time to rank grind as much as I'd like due to work. I mostly play around my work schedule which is currently on call so it can be very sporadic. I currently main mid, but I'm a very flexible player and I love to try out other lanes and try out champs I have never used just to challenge myself and keep it from getting boring. (which is most likely why I'm stuck in bronze 2)

anyway, looking for a consistent team to play with, that likes to play seriously when the time comes., hopefully more on the mature side. thanks
