My opinion:
If time is low u just leave the bomb and dont give the fight, dont fight for the vandal.
If there still is a minute left or something cypher/raze should go mid and hold the cross from B to A, the other hides close A main and peeks off contact. Clove should not go for the vandal as long as chamber and clove still stay close B main.

so 100T just kicking rocks eh?
