Forgot to mention, if you run Aruba (and I'm sure many others support a similar feature), you can check a flag called Broadcast/Multicast Optimization and even when leaving b rates on, broadcast and multicast won't be sent at the lowest basic rate, but the minimum supported rate by the stations connected to a particular AP (so the AP keeps track of the stations connected to him and what is the lowest rate they can do).

In areas with low AP density, it could create issues for devices such as Macbooks.

They have not been a problem since switching to Ruckus wireless. We get a LOT of BYODs on campus, we support TVs, Game Consoles, wireless printers, etc. Most of our slower B traffic has been Android devices.
