tanks not using cooldowns?

[Whiteroom]

I can't do this anymore. After nonstop runs with tanks not using cooldowns i finally had one ask what cooldowns were. After I told them they then only proceeded to use sentinel and rampart on mobs. Thats it. Sometimes used them on boss, but ignored bulwark, clemency, and other paladin tools.

why are healers allowing this?

or when you remind them what cooldowns are, they finally start using them, but all at once, when almost all of the mobs are dead. So many times, pull 10 mobs, pop all CD when only three are left...
