It's similar to the Company of Heroes, who defeated Titan by hurling hundreds of people at him to try and turn him back. Titan doesn't temper, and he killed all but a handful. Regularly defeating something with "significant losses" isn't a working strategy, since there's infinite Ifrits and limited Flames.
