I'm fully aware of the Karma Efficiency of Skills A etc.
Assuming you use it to maximum effect, which, in this case, is 6 Skills at 6 with Specializations and 2 more Magical Skills at 6 with Specializations, it comes out to 547 Karma. Normally, it would only be 6 Skills at 6 with Specializations, and one Skill at 4; that comes out to 469 Karma. Both of those assume one Skill Group at 6, and another at 4.
Personally, I don't go Skills A, for the most part. However, I wanted this character to be very skilled at a lot of things, and Skills B doesn't give enough points or skill group points. I could easily drop it to B and raise Resources to D, which is something I've been considering.
So, yes, I'm fully aware of Karma Efficiency. It's a pretty key thing in most of my characters, and sometimes I choose to break it or choose lesser options for flavor's sake.
