Pro tip for M+: use your cooldowns more

Something that I don't see talked about here is using your cooldowns liberally.

Think of your cooldowns, no matter the length of the timer, as another resource like mana, combo points, rage, etc. Most guides tell you not to cap resources and to use them on spenders. Why would you let the cooldown cap on your timer then? Use them! A dungeon is at minimum 30 minutes (AD), to 42 minutes (KR and SOTS). Divide that number by your cooldowns timer and you can see that you can use it on way more than just boss pulls.

As an oversimplified general statement: Being geared and knowing your rotations will push you through 10s. Actively using your cooldowns will get you through 15s. Doing it as a group will push you through 20s.

Addendum: Tanks and healers: actively planning to use your defensive cooldowns in combination with your healer's externals like shield wall, icebound fortitude, survival instincts, ironbark, pain suppression, will allow you to do bigger pulls too!

TLDR: Use your cooldowns. Learning to plan and manage when you use your cooldowns, especially with your group, will make you a better player. Coordinating that with your group will make you able to push higher together.
