There is some truth to this, as I believe we have said. Using cooldowns when you know you're not going to be taking a lot of damage is a little silly.

However, if you are able to predict incoming damage, then you will maximize the effectiveness of your cooldowns by using them ahead of the incoming damage. With only a few exceptions, defensive cooldowns are meant to head off the damage you're taking. If you only use a cooldown after you have taken critical amounts of damage, then you have saved it for nothing.

Be intelligent with your cooldowns, yes, but first be proactive. Using Sentinel and Sheltron when you've already eaten an unmitigated tankbuster down to 10% of your HP is foolish, when you could have instead used them ahead of time and only been brought down to only 53% HP. This logic applies to white damage. You need to plan for when to use it, yes, but long duration cooldowns (e.g. Foresight, Awareness + Bulwark, Rampart, etc.) are designed to mitigate white damage, and make you require less healing. Saving long duration cooldowns when you are taking even moderate incoming damage (read: all bosses, the start of normal-sized trash pulls, etc.) is poor tanking.
