Is it wrong to ask my buying agent to take a lower comish

[Jacob Miles]

This might rub some people the wrong way. but in my short home buying history, the realtors i have worked with have provided paper work and a way to  get into the house for viewing. other than that i found the house through friends texting me or riding around or Zillow.  The homes I am looking at get a lot of attention (400k homes in need of minor work in highly sought after areas). The homes I'm looking for get multiple offers. Is it wrong to ask my realtor to drop her commission to 2% from 3%. I am already waiving inspections and sacrificing things on my part. why cant the realtor take 8000 in commission instead of 12000?  I minimize the realtors work by driving by the houses before hand to make sure I like the area. we have not looked at a house with the realtor yet. 

My offer would be $4000 stronger if the realtor takes 2% is my argument. Its not 1990 where 3 percent was a fair wage. 3 % on a 4-500k house is insane for paperwork, especially when i find the homes online or driving around and I'm waiving inspection and putting down 20%. End rant. but can i get some pros thoughts on this?

have flipped one house successfully and own 2 college rentals for experience level reference. Thanks!
