I call bs, because that's straight up impossible. If you expect provoke to work like it did in XI then that's not right. It does not increase your enmity with the target, it does something completely different:

1. If you are not the current top aggro target of the mob (this includes mobs that are not engaged/claimed) the it optionally claims, sets your enmity to the highest enmity of your party, +1.

2. If you are the current top aggro target of the mob, then it is resisted and does nothing.

Do not use provoke mid-fight thinking that's how you build more aggro on a mob. It's used as a pulling/claim tool, and a saving mechanic if you lose hate on a target that goes after someone else.
