That set is for if you can't afford any other sets. You probably won't make much money supporting, so soloing is required, since the one's that are buying that set are probably low leveled anyways, that's an option.
I like the guide, jus tlike you said no bullshit, iv ebeen playing for quite a while and i know what the skills do etc. etc. so i dont really need any more info, but as said above by some people, maybe for new players its nice to know what they do, and set stats etc.
