The non humans are so much stronger that if they decided to storm shield all the team member would be wipe out.

The script writer should do a better job in balancing the power out.

Also the distrust and bickering among-st the shield team is enough of self destructive momentum.

They don't need others to destroy them - weak minded and distrustful bunch.

Their defenses are weak and each of the shield members are easily manipulated and will turn on their own team at the drop of a pin.

The show is pathetic. These group should have died long ago.
