if someone picks off meta
try and help them out but dont rage and troll them for example if they go off meta jungle dont be like gg worthless jungle im not leashing then proceed to take his jungle camps you will not win this way and it will actually be your fault not his so dont yes off meta is annoying yes it is probably bad but flaming and not being helpful is not going to help you win and if you take resources from them your even more likely to lose
lastly if you just cant deal with a off meta pick dodge
