There were 3 recent versions of FAW:

DBB FAW - damage was not scaled properly, and was better than CRF III/Cannons in general despite being only a LTC power, being more versatile, being easier to use, not requiring you to be up close, etc.

Scaled FAW - Damage was reduced, making cannons better again. However it was still excellent for clearing spam. This was perfect. Unfortunately this lasted about two weeks.

New FAW - Everything you look at dies.
