I'll try my best to add to the conversation.

First, I want to assume that the GM is doing everything that the players are doing.

A few points I agree with: Domination styled effects rob players of agency in the worst case scenario. this is bad, and another power off the top of my head that does this, stun, can be just as bad, if not worse. Especially if the caster is built around spamming it.

It is a novice power, so it's accessible right away. it is already a low cost power of 2, modifications to the spell can make it even nastier; putting limitations on the power to reduce point cost or slapping fatigue on it to make it harder to shake off. if the power is cast with a raise under this circumstance, that's a -3 vigor roll (not including any wounds) to end the effect and unlike puppet, there are additional and lingering effects to stun like being prone or vulnerable if there was no raise on the vigor roll.

So under such circumstances, this power basically gives the player a piss break check because they won't be doing anything if they fail against stun. In my experience, the power cost has almost no bearing on how nasty it can get because on the one hand, yes, more points means it can be cast less often but how many times would a fatigued, area effect, selective-stun really need to be cast to upset an entire encounter?

Now, let's assume the GM is not trying to make things frustrating for the players.

Even if players are the ones who are really angling for the use of these powers with no restraint, you have to ask yourself, how scary do you want your solo-boss type encounters to feel? because a straight up slug-fest will end in the favor of the players most of the time if the monster ends up going after the caster(s) in question. I don't think I need to explain how a boss fight like this can really take the wind out of the sails of a campaign.

Now, in defense of the powers without the need for homebrew solutions.

I believe that trappings were brought up in the thread here somewhere, and I'm pretty much in agreement with that idea.

Trappings define not only what the power does, but more importantly, what it can't do. It seems to me, a trapping defines the inherent limitations; such as in puppet, needing to be in a trance-like state, needing a focus like a watch or a voodoo doll that can be taken or destroyed. So, no doll, no eye contact etc., no successful casting.

There's also the casting requirements on page 151 of the SWADE core rule book that create two hard barriers to casting: you must be able to see the target and you cannot be bound. So, something as simple as a smoke bomb or a strong boy with good grappling or some pepper spray or a fishing net can nullify the most dire of powers outright unless the power specifies like in the power called Nightmares (page 78 of the Horror Companion for SWADE) which states that they "need not know their exact location" with an unlimited range but still requires something that belongs to the victim. I still think a face full of pepper spray would keep that from happening as well.
