Na. Other blesses like W9N4 would usually be even cheaper. Good E/N blessers are rare. F or W? Not so much.

The real reason that E9N4 is popular is that it can be used for more than just your troops. Forge a shroud and put it on a Cyclops or something and have it go wild! And that is only if you dont have national self-blessing thugs. Because no other bless is as good for thugging.
