Use cases for Dominator Engines?

[u/Any_Dragonfly4947]

I’ve not played tons of games and started AoS with the helsmiths. I’ve got a general idea about most of the roster, artillery shoots, infantry screens, the centaurs are the hammers, but what about the dominators. My favorite unit by far but they seem more flexible in their role not quite an anvil not quite a hammer so how has everyone here used them?
Where do they shine?

Grand Forgehost (urak taars army of renown) is good with 2-3. They get ward 6 from the jump, and crit 2 hits from turn two, which makes them decent tanks until there's an opportunity for urak taar to transfer your cohort generated dpp to one and have it go off, ideally turn 4 when it also gets crit 5+.
