imo this is true from ARR as the reference point. But @SB lvl 70, with the amount of defense & recovery skills spread across healers and tanks & offtanks, I think not so much. People are still going to avoid as much DPS negligence as possible (and dropped GCD is the worst perpetrator).
But in lieu of reducing cost, the other direction could be to justify the harsh cost of both Grit and Shield Oath, like they fixed with WAR more recently.
Give these stances more depth: adding additional effects to more skills, for example (BloodPrice not being such garbage another), where player action is a factor (CD management).
More tree branching design like they got right for WAR this iteration. Some progress on either front I'd enjoy.
