it could work, but actually, it may be a small boost of exp, ropes are 100 caps each, right? Brahmin hides are 100 caps each, right? a +100 xp per tamed brahmin, then one can fuck it up and get another +80 xp with no risk to yourself, so technically it will give some newbs a boost to leveling quicker.
I'm all for it, and as I see the exploit is a positive thing, since experienced players will probably not waste their time searching for brahmin.
And now for something completely different, a brahmin.
