Borderlands 2 talk:Borderlands 2 Wiki
I tried to add a note on the Badass Rank page about the likelihood of the five choices provided when a badass token is redeemed being weighted inversely to the current value of the choices (i.e. if you never select some choices you will eventually see those being offered every time), but the system refused to save it because it was in the "Nonsensical anon edits" category. This seems to indicate that the wiki or some portion of it does not allow anon edits... which will likely limit updates to this wiki and thus its usefulness.
Jambo - You need to be registered to modify I think :-)
