The main problem i have is that I almost never saw those conditions last for even one turn, they would just pass a save and it was like the spell might as well have just missed.

Some of the spells mentioned require concentration. As an example, if you cast Tasha's Hideous Laughter one turn, and then any other spell that requires concentration the next turn like Hex or Bless or any of the hundred or so spells, your character stops concentrating on Tasha's Hideous Laughter, thus ending its effects.
