Nah, the requirements are for picking it. I can't see that apply for just having it from the start due to some other bonus. I am reasonably certain, in universe, that most null wizards would never initiate - I'm not even sure yet it's awakening so much as the opposite - they're just walking antimagic. Only problem is you still pay full magic points for that.
I'm not looking to debate whether Pariah is a decent choice; I can agree it's probably not, but I've already decided to not create a spellcaster. I heard that in my group as well; "just shoot first". I'm in agreement, but the cybered adept is a boring solution to every problem. ^^
I'm debating whether the loss of disenchanting is really worth picking a Mage over a MyAd for the job, given that Null Wizard blocks the main draw of taking a full mage: Projection. For just 10 extra Karma, I got the same capability, minus disenchanting, though I won't actually have to spend karma on it then, and then, I can spend up to 25 karma on power points for actual Adept abilities. I am aware an Adept can fill the same role with an Initiation, but my pool group allows one of those for every 100 career karma, so harmonious reflection will happen exactly never.
In short, my point being: There is absolutely no reason to ever pick a full Mage for creating a null wizard. I wonder if that was really the writers intention.
