Of course it's all about efficiency but if you're not using spells simply because they take a long time to cook and cost a small chunk of elixir you're wasting loot that you could pull in as well. Not every barch raid is going to go smoothly and as planned so a spell or 2 can make a difference between making 100k, and 200-300k. I think we all know which of those we'd rather have.
