Despite my sympathy for Life, I must note that you might not always get the right amulet, but Life's strength isn't just in amulets.
You're exaggerating; there won't be 60 Crusaders against ten Phoenixes, but there will definitely be 40 (you can start building Crusaders around day 5, of course, depending on the map), and they have two attacks, which is very damaging.
Devils will only attack the hero if they get close, and they'll either run into Crusaders or Pikemen, and in melee combat, Devils are very weak.
As for Order, to make Titans and Hobbits strong, you need to cast Accuracy on them; otherwise, they deal little damage.
And Order's mages are generally useless; they're only good for curses and poisons. There's nothing to be afraid of.
Equilibrium is a large mod that changes more than two expansions combined and strengthens not only Life. Calling it a regular mod is incorrect, IMO.
