But then there is the whole argument against prio system (in general) to begin with. Using one set of advancement rules for chargen and another totally different set of rules post chargen will always inherently be troublesome I think :-(
Lots of games have a flat chargen cost with an increasing post-gen cost advancement set up. But Shadowrun is the biggest jump in costs that I've played. 1 Point in chargen to raise an attribute from 4 to 5? Or 50 Karma, which is 7+ runs worth of Karma. The math pushes a player very strongly to max out one thing before starting an investment in another.
One suggestion, change skill advancement to 5 plus what you're going to, and (non-Magic) Attribute advancement to 10 plus, say double what you're going to. Much less mathematical incentive to Max out a thing before buying the next thing. Still going to be the most optimal way, but much less of a Karma difference compared to multiple moderate investments currently.
There are a lot of other ways to handle it. But flatting out the advancement curve in a way that favors mundane characters is my preference. YMMV.
