Or at least request the person stop playing ranked immediatly? Is there a limit on how bad you are allowed to be, in relation to what tier you are in? Is it really okay to not be able to do the most basic, simple things as a high Diamond player?¨ https://www.youtube.com/watch?v=8RNgyRkVnrQ
Never
Why flame? It serves no purpose except for a brief, fleeting sense of personal satisfaction if you're into that sort of thing. And it backfires if you're being trolled, because you're giving the troll what they want.
If somebody on your team has basic knowledge gaps, the best thing you can do for yourself is to try to educate them with time remaining to save the game. Otherwise the only "benefit" you can get by berating them is to make them feel worse.
I had a Nasus in my game not too long ago who, apparently, didn't understand that his Q needed to be stacked on minions to actually deal damage. I was pissed; Nasus stacking his Q is a fundamental component of his kit and one of the most widely known mechanics in the game, and a Nasus player without that knowledge is considerably gimped. I was going to probably lose due to my top laner having a glaring knowledge gap about his own champ! But I simply said "hey Nasus, your Q permanently gains damage if you use it to last-hit minions, and you'll need that to be relevant in the late game". Flaming him wouldn't have helped me at all.
I honestly forget if he got good mid-game and was relevant to our team fights, but he did thank me, and he did start stacking his Q.
You are not allowed to flame, ever. That is what the rules say and that is what you should abide by if you don't want your account banned.
I thought you could flame if you were Annie, Brand or Fire Elemental Lux. :/
Keep it in YouTube and you can do it all you want. I find this kind of funny and as long as you're not harassing the guy in the game, well, go for it lol
I often tell people who are clearly tilted to take a break, but I rarely flame.
When you are
