Yes, seems quite useless and unnecessary function to me. And moreover when some rookie views these options, he is fooled as he must be interested in having strength, defense and gold, unknowingly that credits can get him better legendaries.

The uselessness of this option is known to experienced people, but not to the newbies. So i too would request to remove such options. (Though Chris Sir might have his own opinion, he would be willing to generate obstacles in such brain tricks for newbies.)
