I've found that Shees can be good and cheap anticasters sometimes, when your oponent only has a few casters, cause AMS prevents and also removes neg. buffs. But it's stupid to cast AMS on an enemy unit with a pos. buff, cause you will be giving the unit free magic immunity, thats the bad part of it, but it has saved me sometimes when I do the Howl/Curse combo.
BTW: Could someone please tell me what is the "barrage" ability, cause my WE is in spanish and I cant get the translation, thanx
