I'm not sure the BLM example is good - healers have that already with their oGCD and instant cast heals and optional Swiftcast use. (BLM is praised a lot but...)

I think I would argue that meaningful choice cannot exist without depth of choice. If there is one right answer and every other answer is wrong, then there is no choice. There have to be more than one "right or close enough" choices, else there is no choice. Imagine if BLM didn't have Thundercloud or Sharpcast or anything other than Scathe and Xenoglossy (that you can use all the time, not limited by stacks). That wouldn't be real choice, since Xenoglossy would always be the right answer and there's no condition where Scathe would be.

I also think it's interesting two replies back to back say that Broil IV vs Ruin II both is and is not a meaningful choice...
