When it comes to Hunters, I also figure it comes down greatly to how they were trained, which Lodge/Family they are part of and what they hunt, as well as raw willpower. A combination of that would make individuals more or less resistant to the compel ability, perhaps even some witch/voodoo hexes. Genevieve doesn't have any proper Hunter training beyond some cursory lessons, and is not affiliated with any Lodges, so she leans heavily on her military background. Someone like Alden or Maximus with proper training and equipment would start out with the knowledge of how to combat such things, so they have an innate advantage before any non-Hunter training comes into play. All three of them have their own resistances and techniques, probably quite capable of fending off a younger Vampire's compel and mid-range ones if they are aware of them. Can't speak for Monacho or PrincePierce, but I've put down Genevieve as quite resistant to the compel in her own way, up to an Elder. That's largely due to her training and a mental technique that she uses when she feels it coming over her.

On Regeneration, I do think that Were's should have the stronger side of that ability. Most fiction describes them as essentially living tanks, able to take excessive amounts of damage and recover from it in relatively short periods of time. It's why we thought it appropriate for Blaine to have largely healed from the silver bullet she took in the battle in the forest, though still somewhat limping. A normal person would have sustained serious injury if untreated, and might still be recovering in the hospital if they were shot like that. Rolling with a factor of ten might be a tad excessive, but since we've already discussed them being able to regrow limbs, it might not be lol. Definitely agreeing on the point of regen being stronger while shifted though, maybe even to the point where injuries sustained in human form might still leave scars?
