There’s so many examples of different comps to look back on as examples of how people use energy neutralization.
As a general rule of thumb, the slower you can kill ships, and the fewer ships you’re facing, neutralizers are better. They’re devastating 1v1, and for crippling key ships you’d struggle to break with raw dps (like a fax, dread, rorqual…), but when the outcome of a fight is decided in less than 30s they’re unlikely to be a major factor.
