Fixed it for you. The only way for that to be fact is if you were talking about predetermined spells that you would have no matter the choices you could make. I.E. cleric and cure spells, elemental savants and SLAs, druids and summon animal (if we ever get druids.)
Fact: Haste is useful in all quests, however, to what degree is debatable.
Fact: Depending on build and playstye, other spells may have a greater "useful" value than haste.
Opinion: Repeating yourself does not improve your point of view.
