Build points

[Kaasovic]

But anyway, why is this system of abstract points required to build something that you already brought in? Do you somehow acquire knowledge of how to build more of the exact same barricades as you survive longer and/or kill more enemies? Of course not. None of this system makes any sense.

The build point were introduced to limit the amount of barricades being build. Before the support overhaul was integrated it was very common to see people walling of everything and turn it into a ranged fest, basically requiring no skill at all. Alternative methods of achieving the same cause were looked into as well, I.E. removing ranged classes, removing barricades, etc..
I think you are more then capable to view this matter in a more objective way instead of the ideology you are currently blinded by and understand that rangedspamming is not something the development team wants.

As for the current placement system (spawning the construction site beneath you); we are aware of the limitations that this system offers and we are looking into ways that to improve it. Sadly I am very busy with my job at the moment and would like to apologise that such feature might take a while before it is implemented.
