Ideally, I want to assemble a dream team of a few heroes and only play with them, but that would create elemental imbalances. Optimization isn't a major concern; I just want to avoid complete failure.

You can only carry that for a short time, especially at the beginning. Even then, it's not recommended. Unless you're lucky enough to pull a Grand Order. But then you'll have to choose heroes from different elements.
