Nope, problem's more fundamental than that. You have scalar effects(e.g. the 3 stages of Fear(semi scalar), ability score damage), staggered binary effects(nothing happens until a certain point, then effect, e.g. hp, nothing happens until 0, then you KO and die) and a binary effect(Save or Die, Save or Lose). All these have around the same odds of success.
When such a choice is available, the most effective is invariably the binary option, followed by the scalar. Binary effects usually upsets the game most, so putting them all into scalars seems to be the best bet.
