Provoke had a huge range so use it to pull patrolling enemies (read: Aevis in Stone Vigil). Some patrols hit like a truck so ideally you want to be tanking them individually.

40s cooldown really is nothing so you can afford to use it on every patrol. I found 60s to be the golden standard for 'once per every trash pull'.

Another thing you should keep in mind about provoke is that it matches your aggro to the current highest aggro and then gives you an infinitesimal amount of enmity on top of that, so if you provoke something, just keep in mind that the moment anyone does any action at all, from auto attacking to using buffs, you will lose aggro if you don't generate more.
Also, if you're looking to rip hate off of other tanks, build up to Rage of Halone, provoke, then use Rage of Halone to help keep aggro.
