The sad thing is, I feel like this thread wouldn't even exist if the augments on Steadfast Shield weren't the worst thing since sliced cat poop compared to the augments on other items. If the listing on BG Wiki is correct, the only path with something super-useful on it provides a whopping 4 Magic Defense Bonus.
The base shield is very good. That, along with occasional use of Adamas, could have worked as a stepping stone for Paladins. But, the poor selection of augments reduce the shield to an option for Paladins super-tanking in Rieves to see if they enjoy the job or Dark Knights using Requiscat on that annoying Cerberus in Bhaflau Remnants.
