OK, Iron Discipline makes Comrades resistant to Fear and Pinning and Into the Jaws of Hell makes them immune to it.
So what???
They only fail Fear or Pinning is their associated PC fails. If their PC suffers from Fear or Pinning and they don't, because of these talent, they still can't really do anything… because the only actions they are capable of taking serve only to provide their PCs a bonus to actions which they are unlikely to take while Pinned or under the effects of Fear.
So why would anyone take these talents? What am I missing?
