You are also forgetting that you can make 9 per invent of teak (for 2700xp) and only 3 with oaks(1200xp). Even if oak doors were twice as fast to make as legends capes (they aren't), you still come out behind XP wise. You can concentrate on making money for money's sake and con for con XP and come out ahead with teaks any way you look at it. with a butler oak is faster than teak you cant make 9 legend cape 9X3=27 you need saw,hammer,cape,cash if using butler
