How to benefit the most from drawing spear?

[Sylve]

Anything labelled as an Ability should get the benefit. I know Essential Dignity goes to 32 seconds when i have it on myself, So i imagine it also works for things like Bloodletter, Howling Fist, Elixir Field, Gauss Round and perhaps Ricochet.
I could be very wrong though, my AST is only 42, but enjoying it a great deal currently.

It does, but those abilities have lower cooldowns anyway, so the benefit is marginal.

It might also mess up their rotation if they're popping certain oGCDs in line with buffs.

At the same time, it may help to line said Abilties up better. Even shaving a couple of seconds off a cooldown can lead to a good chunk of extra damage over the course of the entire fight if you do it regularly enough.
I'd say it would be worth using when its available.
If anyone does have an issue with the lowered cooldown not lining up 'properly' with cooldowns, nothing is stopping them from simply holding off for a couple of seconds to get it lined back up.
