Fortnite AIM?

Hello in fortnite aim course you know that if you have to with a pump to edit the walls on eg a window and you have a bot killen must be in there or otherwise you should aim at or without and should aim in pump fights with fight with the opponent or without.

So I aime with the pump almost always, but I think everyone else!

I do not aime because you should not aim in the shotgun because you are a very easy target if you stay in front of the opponent.
