Ideally bots should not shoot at breakables if they don't need crash breakables.
I mean this - if bot needs to go throw some glass (or some other breakable) from WP x to WP y (and there is a connection between these WPs) - if bot detects it as an obstacle to go - then it should shoot at it. It's human like - we do the same - we shoot only at these breakables they are some obstacles for us. Don't need to shoot at all possible breakables arround.
