Xylocaine issue a non issue?

To the boxing community(not including fan's) and media Mayweather using Xylocaine is not an issue,yet in this forum some people act like it helps turn him into superman.If a pro boxer used something to make him not feel pain in his hands wouldn't he destroy his prized posession by time a fight is over? If going by the logic of people who think it turns him into the man of steel where is Roach,Pacquiao,Arum calling Mayweather out for illegal practices?Wheres the media,one respectable expert,boxer giving Mayweather grief regarding the issue.Can anyone give me one article by a credible source accusing Mayweather of any wrong doing(articles created by fans at boxingfanhouse doun't count)?
