About your friend : https://gtm.you1.cn/id/348600021/ .
Idk if you are good friends or not, but your friend has to stop playing Dota. He has 16500 hours and is still stuck in guardian. Even my dog could do better. Be a good friend and tell him the truth that no one likes playing with him. How can you be happy if you keep losing. Your friend does not have the mental capacity to play Dota. He does not understand how to play, does not have any idea what is happening and what to do. If he does not quit, tell him to watch pros from youtube and at least learn. Or he should play non-competitive games like minecraft or dressup. Introduce him to single player games, but i still think that he will find a way to get stuck.
So sorry for putting this in your account. This is nothing against you but your friend. Please let him know of this comment.
