I need some help understanding when to go into the tunnel for B site on Fracture.

Everytime a teammate suggests that, I just think to myself “well why?”

If we’re fighting B Main and Arcade and someone says “Let’s use the tunnel”, I just think, let’s just fight them instead.

If we want to rotate to A or something, just rotate through spawn.

Sometimes they’ll say “let’s shift walk” from start of round from B main to tunnel. I think, well why didn’t we just start arcade side

My friends and I are Iron-Silver so we don’t know what we’re doing
