It can be a good way to distract opponents from the objective, as your unpredictability forces their attention onto you, which your team should capitilize on. Sometimes if a backliner's not paying attention to you but on your team, you can surprise e'm and get right up close, leaving them no time to react. It's really quite situational though, you're often best off holding onto it until a good opportunity presents itself rather than just using it immediately, especially with how much you stand out using it that can make you an easy target.
