If she's wielding a monowhip (or even a gun), STR wouldn't factor at all in damage, but still would for things like encumbrance & skills (which most of the Athletics group uses).
So, she's planning on carrying a lot of that Mage gear that's so heavy? I see.
It's a better deal here (Karma wise) to raise the skill than the attribute (for instance you could have rank 4 Athletics and 5 STR for the same pool... and net 2 Karma - or 6 if you count Flight...) and since we've already established she won't be using the attribute for damage, I really don't know why she's invested in STR as much as she has, even at 5. REA is way more important (IMO) over STR for this character for it's passive dodge and initiative benefits.
As for BOD, is the soak die that much more important than being able to wear two higher armor without encumbrance and the extra hit box?
You're paying the same 10 BP for 1/2 the "benefits" of that 10 BP. I'm not saying one aspect of BOD is more important for you than the other, but my suggestion definitely gives you more bang for the BP. Especially if you were to buy a 7 with 10 BP.
So yeah, drop STR 3, bump BOD 1 and REA 2. Makes for a pretty good Combat Mage (don't forget to drop that MAG 1, bump EDG 1 and get a Power Focus 2 instead, yea?).
I'll certainly advise on the skill portion though. Keep in mind I did state I am using the Ends of the Matrix rules, where hackers can force a matrix connection with anyone in LOS; hence the choice in Matrix Stealth to avoid being visible in the Matrix.
Again, hopefully your group has a Hacker to take countermeasures against this. It's not worth spending 6 BP (12 Karma) on being crappy at Matrix Stealth. Purchase it post chargen for 6 Karma if having her Commlink disabled is going to cripple her (or forget about trying to be something you're not and get Mindlink and not have to worry about it).
Also, just noticed this. She appears to have taken the Athletics Group at 3, but somehow separately raised her Gymnastics rank to 5? I don't think this is allowed. And now that I think of it, dunno why she would really need Shadowing, isn't that what Watchers are for?
