For multicast the situation is the following: the selection of available data rates affects all stations. If I drop the lower data rates to force multicast traffic at 11Mbit/s, then the stations close to the sender will be able to receive a video feed. Stations further away won't get it, but this is a trade off between data rate (e.g. quality) and coverage. However, I'd still like to reach them over unicast, even if the data rate is only 1Mb/s. The current approach would prevent this, despite the fact that it would be physically possible. So, I would really prefer a solution were multicast and unicast data rates can be selected independently of each other.
