Is a Promethean, Vampire or Werewolf really going to be that much better with more power stat instead of merits? Long term, they're ahead a chunk of XP. But as far as playable characters go, I think the merit guys have a much better time of things.
Raising Gnosis works for mages, because mages have one BIG thing going for them, and raising Gnosis makes that big thing better. It's possible to go without, if you're planning on using few improvised spells, but there is a much more noticeable mechanical sacrifice.
