Whilst I don’t use Clemency terribly often myself (and pretty much only in DF dungeons) it is, and will always be a niche part of PLD’s defensive skill set, the value of which varies depending on the situation at hand.

To automatically cite occasional usage of Clemency as a lack of trust in Healers or wasting other people’s time is incredibly disingenuous to say the least and quite one sided.

Perhaps the PLD is short on cooldowns for whatever reason, or perhaps it’s a pre Holy Circle duty and they feel it’s the best expenditure of MP vs single target hitting 1/10 mobs or sometimes the healer is doing the limbo game but lacks the experience/skill to properly manage this.

No doubt there are PLDs who take it too far. And the Healers getting uppity about trust issues are assuredly the minority but to those that do... if you want the tank to trust you, then trust the tank to use their entire skill set as and when they feel appropriate rather than immediately viewing it as a slight against you.
