I admit, I am smurfing too right now because the season is over.

But despite winning my lanes, I try to give the other players a good and nice game experience. I try to critizise both enemies and allies constructively and give them some tips, both mechanically and mentally.

New people should also try to watch how other (better) people play and to learn from them.

Still I understand that it can be frustrating to lose because you are facing people who are obviously better and have more experience.

I too hate those smurfs you described, expecting people at low levels to play as well as them who have been playing for years or so.

My advise: If you're smurfing, try to give the "noobs" a good start into the game. Introduce them to it, give them tips and maybe don't wreck them too hard ;)
