[Reboot]

Mind Blank's advantage over PfE is that it blocks a whole pile of things that are [Mind-Affecting] but not actually mind control (e.g. Power Word X, Phantasmal Killer, Sleep, Fear), as well as divination (it also lasts longer).

Also, there's the "supresses vs blocks" thing - you absolutely can get dominated before or during the duration of PfE, and it will (re)activate the round when it ends or is dispelled. [And remember that, even if Rich isn't following it, per RAW vampire domination doesn't end with the vamp being ended - you need to make a secondary saving throw, have Break Enchantment or similar cast on you or wait out potentially a couple of weeks following their last orders. Mind Blank actually prevents or ends it entirely.]

PfE and MCaE both would've been stripped away the moment the dwarves entered the structure through the orange barrier.

Not if they were cast between the barriers. They knew about that, and no vampire actually tried to dominate anyone outside it anyway.
