Topfeeding has nothing to do with rank or NW. When scrubs hit top players it is called topfeeding.

I don't topfeed bots when I am lower NW than them, I grab them. Because I am better than the bots. If you grab the bots, however...

Hope this clarifies thing for you.

Why can´t you get t10 without getting up in the middle of the night? Ahh.. got it. You are really bad.

If you try you might get better. I encourage you to do this. I'll even help you if you want.
