Gotta say, if you have any doubts or hesitation about trying this delightful little tool, you can rest easy with giving it a go.
I'm a mid tier player. I don't citadel people across the map before they have even been "detected" I slowly get further into the map until I see some enemies and then slug it out. Usually with a really good game every now and then.
This thing has made my play much more enjoyable. Much more competent now. Not a god, but better.
Totally worth it.
