Could you change the way this area looks if you're not going to make it reachable? It's disturbing to me.

Same thing over here, why block the access to this little spot?

I can stand on this "tube" (don't know the word) but i cant go further forward because an invisible wall blocks me? Please, it's so incoherent :(( Make it visually coherent, if you dont want someone there, do like a building please :(

The purpose of the area I aim at is still obscure for me. If it could somehow link to the lobby without opening too big sightlines i'd be happy.

I think with your current 2nd point that pushing out of it will be extremely hard, because from this position it's possible to control every access, and because the exits (except under) are both very narrow. I'd suggest widening up the doorways.

I think pushing from mid to second could also be very hard, because as the attacking team, it's very long to rotate between under, the left side, and the right side.
Keep up the good work!
