I did lower the priority with the 1x1 clients with Yagis but then I started to think that if the AP did get congested, those clients would suffer first.
I am also using 5MHz bandwidth for improved distance and noise immunity which lowers the total AP capacity. In the past, with different and older 900 AP's, I have watched customer demand for bandwidth increase to the point of congestion. I wanted to avoid this scenario with the UBNT gear at all costs.
I am not sure where the point of congestion will be or if I will ever reach it, but it is a very competitive world and losing customers will cost more than the upgrade to Rockets and Dual-Pol Yagis.
