new viper wall

why do teams use this viper wall https://imgur.com/a/GnKY2Am

Idk ik T1 uses it

Very similar to default one, but slightly different. Imo the main difference is that this wall has an additional purpose - to help take A main without having to rely on other utility. That is assuming there is a gap to enter A main, it's a bit hard to see from the screenshot, because harbor has a big head

Can lurk up A main and clear behind the right tiddy on site for a safer plant.
