And that's exactly my point. Unless you're giving bosses high damage phases that last close to 45-60 seconds, there's no need for Hallowed Ground, Sentinel and Rampart to have more uptime.

And let's not act like the decision is difficult. You get ganged up by a pack of mobs, you pop a defensive cooldown. Boss enters high damage mode for however many seconds, pop a CD. You have a close call and want to buy the healer some time to get your HP up, pop a CD.
