PiNoY had 1 sub only for a while and did pretty good. And yeah it's possible, look at Mau5trap, no subs, no allies, and 300 hours of fort time. Once in a while you may see a new face but really it was the same people you'd see at swamp taking down VG. But with the same 25 anyone could probably do it, it'd just take an extremely long amount of time lol. And noob recruiting I consider is recruiting random noobs who walk inside the tower your at. If a newer player asks if they can help I don't see the point in saying no, I like to give everyone a chance, I don't consider it noob recruiting if the "noob" asks to help.
