if you gotta troll...
...PLZ DON'T DO IT BOT WITH SOMEONE WHO ISN'T PREMADE WITH YOU! just troll mid... or top... or jungle... not adc or supp... only if you are premade with the one who's gonna lane with you... cos you're gonna make the game frustrating for both you and the other guy... for him, bc he gotta lane with a troll... for you cos he's gonna blame you for everything. just... don't... you wanna thresh adc but you have less friends than amumu? thresh full ad top... you wanna go full ap with a mid laner but you say "supp" ? go mid! i like to troll... but i don't force a stranger to lane with me. i played draven jungle, lb supp, soraka adc, crittlesticks, apc kathus (that worked surprisingly well) ecc... but i never forced a stranger to lane with me. (most of the time i troll in a 5 men premade)
if someone trolls and goes adc/supp should be premade with the other one. cos if you go adc and your supp goes full ap and steals kills it's not funny... or if you go supp and you get a yasuo adc it's just frustraiting...
be kind... don't force a poor adc to lane with a troll... don't be that kind of troll... be the funny troll...
