Using macros has a very significant impact on your overall cast throughput, it's been a long time since I mathed it myself, but from memory it was somewhere in the region of 10-20% all told. It's important to stress that this only fully applies if you're keeping your GCD rolling through. If your mobility impairment is consistently preventing you from rolling your GCD then that changes things. At that point the only real issue is that you'll generally be paying a small time penalty any time you try to reactively bop someone with a heal or other ability through macros due to inevitable downtime.

In BCOB I prog raided as SCH using macros to force my fairy to embrace the MT whilst I did just about anything else. As part of my preparations for SCOB, I experimented with other ways to force embraces including using a free spinning mouse wheel, G25 pedals and a stupidly expensive Corsair keyboard that had a ton of macro keys.

To my horror, I found that using in game macros was quite literally costing me somewhere in the reason of 2-3 full GCDs per minute from memory. Switching to pedals and running the macros on the keyboard instead of in game was a mighty throughput improvement.

As such, my recommendation is to go find a target dummy and experiment with what you have at your disposal. If you can find someone to log your throughput, even better.
