PSA: The jungler is not immune to blame
If you gank my lane when there's an huge minion wave at my tower and I don't follow up on your gank, it's your fault for not analyzing my lane before you gank.
If you gank at 40% hp or lower and die it's your fault.
If a lane is getting heavily pressured and ganked and all you do knowing that information is farm your jungle, not take objectives, gank other lanes, counter jungle, push out a lane, it's your fault.
If you over commit to a gank and the enemy already blew their summoners and you dive them then die it's your fault.
If you push the laners lane when they recall and or die causing your wave to go to their tower losing your laner exp. Only exception is pushing lane after a successful gank or holding a laners turret.
If you get an objective stolen from you as Nunu it's your fault.
