Absolute skills

Just don't forget the topic; we're talking about the ultimate ability, not a 10-minute skirmish. Admit that "fight to the last" will be completely useless to you after 1 month of gameplay, and time will have been wasted. I prefer developing things that will be used until the final victorious battle, rather than fighting for defeat.

Admit it, obtaining an ultimate has 3 problems: time, the drop rate of necessary skills, and the need to sacrifice good abilities. So, the question of how useful it is for developing necessary abilities is very relevant. IMHO, "fight to the last" is actually quite decent. After all, the living don't have ghosts that you can easily use to shield skeletons from powerful high-level creatures. And a single unit that always survives is a serious tactical asset. Plus, the subsequent stubborn defense stemming from it isn't useless either. It's a shame, of course, to give up evasion, but it's not critical.
