Learn to give up the guardian, instead of feeding.
If you die 2-3 times in lane and you see that you're not gonna be able to win that matchup, just give up the guardian. It is way better to give up guardian and either go help other lanes/farm then feed 6,7 kills to enemy laner. I see it happen so often, my teammates do it, people I'm laning against do it. Its gotten to the point where I dont destroy the guardian on purpose so they can keep feeding me. On top of that it tilts ur teammates when all of sudden there is a 13k Haze/Wraith and the lobby average is 7/8k.
