If Kroot really lose a point of STR then it's easy to get outraged if looking skin-deep, but if you think a bit further:
-It's a good sign Kroot are finally getting their evolutionary adaptations as seen in Chapter Approved, of which one of them were +1 STR (they'd been eating lotsa Orks.)
-They will be cheap.
Both are reasons to rejoice from me. Can't wait to get my Kroot with Hyperactive Nymunes (Fleet) - assuming of course the codex passes inspection and is buyable on a moral standpoint.
I've had recurring nightmares
That I was loved for who I am
And missed the opportunity
To become a better man
