SR5 is curious, power-wise. A lot of things seem more powerful than they were in SR4, but only on a flat scale. SR5 characters are actually less powerful compared to the rest of the world. Someone starting out with a skill of 6 or 7 is still good, but is nowhere near the best in the world any longer. One thing that remains the same is that with such wide-open character creation systems, you can make characters of widely varying effectiveness. And despite all of the nerfs, you can make powerful builds. Even with the core book alone, you can start out with 12 power points, 12 Agility, etc.
