I met the silent newbies many times until I stopped telling them little tips and just let them be. But then when that happen, the problem is changed from the silent newbie to my angry teammate (my classmates).
And the mad pro, I.. Seen them too, I guess. Those guys I met wasn't really a "pro", they just better than me but still not a pro. Thankfully there are still people like the friendly pro who don't insult you and bring up your mother when you do a little mistake. GG!
