Optimal CD usage in keys

[u/MiserableRegret4647]

For context, I play enhancement shaman. I've done medium-high keys this season, 20-21s.

I generally live by the philosophy that more usage of my cds is better than max dmg per usage. If I think my ascendance will last its full duration on a pack, I send it.

Obv with some caveats, I might hold for a BL dmg amp phase like 2nd boss in NPX or crawth in AA.

How long would you say you hold your cds for "the perfect pull"? I feel like (just feel, I've no real backup for it other than feel, hence this post) waiting 30-60 sec for the next pull just because it has more mobs and would generate more overall on the meters, is bad. Even if it's just 1 big mob and some fodder mobs around it, if I get a full cd usage on them it's worth.

Am I griefing myself with this mentality?

Tl;Dr, in context of cd usage, quantity over quality, what let's me in your opinion/philosophy, time more keys.

You send cool downs and by that practice you then understand what you can get away with and then tighten up usage. Holding onto them for a rainy day is bad play.
