One of the biggest issues most people have with non-ambush based UAC combat is that it takes much more time against a single opponent compared to other combat forms.

A suggestion I have for the efficiency is to add a new component to the tier up process. Where after so many ranks of training you start getting a percent chance to automatically follow up with the blow you have an opening for. So for instance at 25 ranks you may have a 10% chance to auto launch the next attack for reduced RT when the tier up message occurs...creating a chance that you can do up to a three blow combo against your target.

As your unarmed skill ranks progress the odds of getting auto tier ups would increase up to around 30% at cap, with some bonus provided by punch, kick and grapple mastery.

This would essentially be the UAC version of MSTRIKE built into the UAC system to help equalize the UAC weapon styles with the other weapons.
