i got a question for you dps..

[Aiselia]

To answer OP's question. Assuming a single boss encounter, if i have to use quelling strikes so the tank could keep aggro on initial pull, the tank isn't do his job properly.

If you're not using Quelling Strikes even if you don't need to, you're not doing your job properly either.

There is no reason for me to use quelling strikes if the tank is holding aggro confidently. If I use it randomly just because the cooldown is up, I may not be able to use it when an emergency arises, such as if the tank dies, or an add spawns

There's less circumstances to even need quelling strikes either nowadays; the boss splits with a mirror enmnity list, or add spawns need to be fixated on a dps anyway.

And if there was, you're better off using it for add spawns where they need to die asap as well as the tanks having to take immediate aggro on it.

I'll precast it for my opener but past that I won't use it unless I need to. Animation lock is only like .2 seconds or so, which is pretty negligible, but it's a decision between .2 seconds of doing something that has an effect or .2 seconds of doing something that has no effect. Again, it's negligible and I get that, but I'd rather have a negligible gain than a negligible loss.

an add spawns

you're better off using it for add spawns

Assuming a single boss encounter

'Round my parts, "single boss encounter" means that there's only a single boss for the encounter, no adds, so you wouldn't need to save it for adds in a single boss encounter, so, I mean, unless "single boss encounter" means something different for you, there's that context.

If I use it randomly just because the cooldown is up

I'll precast it for my opener but past that I won't use it unless I need to.

so the tank could keep aggro on initial pull

Initial pull isn't "using it randomly". Initial pull is where openers tend to happen.

Hooray for context.
