You would not want to use it in ideal situation. Just that in situation when u need to save enochian due to movement, you can use Scathe + F1/B3 instead of transpose.

F4 F4 F4 ---> can't cast or finish casting F1 due to mechanic forcing you to move and timer is running out ---> Move out of AOE + Scathe ---> F1 F4 F4 F4
