Before the build menu was moved to the new radial style, you could see your squad had "X/20" built for each fortification type.
After the update to the build menu, these numbers are now "invisible" variables for your squad, that you have to track by A) approximation, and by B) hope/luck that your squadmate didn't use them all up.
This frustrates me, because it often leads to me redoing the input to make a structure over and over, wondering why the hologram wont appear, and right at the critical moment, leading to lost firefights.
In those cases it turns out my squad collectively put down all 20 of a thing. Usually it's me using up most of them and when I hit the limit I might go "oh, that makes sense, feels like I put down about 20".
I can't tell if my squadmates are "builders" until we ** run out** since the number was hidden. There is the corner notification when sq. points are spent, but it's so tiny and out of the way, that I don't even notice it happen most of the time. A lot of players just run n gun while barely using structures.
You used to get a little bit of info about your squadmates tendency to build or not build, just by glancing at the numbers when you build stuff throughout the match. I see the number is higher than it was a minute ago and go, "Oh some of my squadmates like to use hesco walls and and the peek-hole walls? I won't use up more than 6 or 8 then."
Now with the hidden info, I have reduced ability to be economical with the squad's resources, and it's so much easier to accidentally use up all 20 of a fortification. I feel like an asshole when I do it because I know it might be getting my squadmates killed. Maybe they needed to put that wall down to defend from a sniper, I don't know.
Maybe needs to be on a per player basis, not per squad. I'm personally fine with people building a lot and making huge forts, the problem is that one can selfishly deplete their squad and go find a new one to get resources from, for their build project.
