Don’t need the respawn ( stupid smartphone keyboard , not remake).
If they have 30 teams and 15 are one 5* 4.80 hero Trap teams, that means 15 of their teams are equal in war points to 3 full five 5* 4.80 teams. So the other loaded teams are worth 83% of the point. If you ignore the trap teams, the loaded teams revive twice for 249% or 4,980 war points. Use war energy #4 for a full enemy kill and it jumps to 349% for #5 & #6 energy.
But the enemy still has to spread its war energy among your 30 Strong/ Scary defense teams.
