I've seen this come up a few times and the main push back against it is screen clutter and performance issues. I can understand where they're coming from as someone who used to have to use integrated graphics to play. Going into any main city where there were a lot of people caused my computer to slow to a crawl to the point that I had to leave or risk a crash. If this could be implemented as a client side only option then I'd see no problem with it so long as you feel your PC can handle it.
