As for how it could
potentially break char gen, and I stress potentially, as I don't see may people making a character with this exact assortment of stats (Though I suspect it would make a killer missions face)
Sum 2 ten A(4) in attributes, A(4) in skills, C(2) in Rescources, E(0) for race and magic (Only matters because humans get 1 special at choice E)
Rating Cost
Bod 3 25 karma
Agi 3 25 karma
Rea 3 25 karma
Str 2 10 karma
Wil 5 70 karma
Cha 6 100 karma
Log 5 70 karma
Int 5 70 karma
Edge 3 15 karma
410 karma for the attributes and edge (And I'm sure if I tried I could raise this eve higher)
The skill could look like this
Rating
Skill 1 6 42 karma
Skill 2 6 42 karma
Skill 3 6 42 karma
Skill 4 6 42 karma
Skill 5 6 42 karma
Skill 6 6 42 karma
Skill 7 6 42 karma
Skill 8 4 20 karma
group skill 1 6 105 karma
group skill 2 4 50 karma
469 karma for skills (This I'm pretty sure is the worst case scenario for karma)
Rescources 140,000 70 karma
949 karma so far and I haven't even started on knowledge skills and contacts
As I said, this is a
potential problem build character just thrown together in a few minutes as an example, as metahumans have to spend points in race, it's less of an issue for them, but I can see where the potential human abuse ruling came from.
Now, I will freely admit that I haven't compared this to the potential karma cost of a standard build character under the base priority system,I would expect that there are already builds that far exceed 800 karma, hence why it was ruled to allow karmagen as they may have a tendency to be a bit weaker.
But I would recommend that people try to make their concept character in both systems to see which way it comes out more to your liking
(edited to include potential numbers change for prionic6 post)
But to compare
Human mundane chars would typically use E for magic and D for metatype, resulting in EDG 5. Giving up two of those edge points to get 4 points of attributes or 10/5 skills or almost 20000 ¥ is pretty much a no-brainer and very powerful.
So resetting the priorities to Standard; A(4) in attributes, B(3) in skills, C(2) in Rescources, D(3) for race and (E) for magic
Without redoing the entire thing, keep the attributes the same, raise edge to 5 (increase karma cost by 45)
Only have 6 skills at rating 6 and 1 group sill at rating 5 (decrease karma cots by 142
End karma cost becomes 852, a difference of 97 karma
