Using the Direct option lets you basically do a teamwork test for skills you don't otherwise have. That is pretty darned useful. The trick is implementation, you really need to talk with your gm about how they interpret the rules. The target has to accept you as a temporary leader, and its a little vague about what that means. If a pc can do that voluntarily you basically become a Shadowrun bard and can help with just about anything. If not you have to make a roll vs their willpower first, which in combat means its now two actions, it may not be worth it in terms of action economy.
