Players who refuse to play their lane
Can anyone from Riot (or with links to a Riot post) please provide some information on how this should be reported to best bring it to Riot's attention? Obviously not for one game, but to ensure that the report, along with others (if they happen), is noticed? Games where the support is top-lane more than they are bot-lane are not fun for the ADC, nor anyone except maybe the person trolling by doing that.
I usually just report for negative attitude with a very detailed comment, and then check verbal abuse and intentional feeding if they also apply. Is this the best way to do it? Does it qualify as intentional feeding even if they never ran into fights, etc (as they are leaving their adc in a 1v2 lane the entire game with no help)?
