PSA: Divers generally don't go tank when behind

Divers generally have 1 rotation spell and becomes useless during the cd. When diving backline, it basically means death after the combo unless the target is dead and the fight is won. If the diver is behind, building tank will simply make it even more useless in teamfight, as it doesn't have enough damage to even threat the enemy backline, and being slightly tankier against fed enemy's damage makes not much of a difference. If you can build dmg and do 2 dmg to the enemy backline then die in 1 second, it is better than going tank and do 1 dmg then die in 2 seconds. Accounting in factors like lifesteal, building tank is basically always worse when behind for divers, since after your combo, the more health you have the more healing the adc get, while you are doing basically no dmg with slow as fuck auto attacks.
