Do you automate EQ?

Should you automate EQ to let sounds fill up the space if nothing else is doing the job?

So in busy bits of your mix, the EQ for each channel is different to sparse parts?
Puzzling over EQ, because if there are lots of elements on the go you can EQ the mix to sound tight, but then when elements break out everything sounds weird. Like when you isolate a channel and in the mix it sounds great, but on its own sounds weird.

Argh.

What else do you automate? Reverb? Panning? Filters? Everything?

I tend to just stick to filters and wet/dry effects, have never really done much eq automation, or even much volume automation.

Probably should do, curious how other people work.
