360 torso twist does not mean it has flip arms.
The situation as I have understood it is that Siilk observed the Raven in the following conditions:
1) Legs facing him.
2) Torso facing AWAY from him.
3) Shooting at Torso correctly (in regards to point 2) damages back torso.
4) Raven returning fire at him.
Point 4 makes no sense in regards to point 1-3 and that is the issue Siilk is bringing up as suspicious behaviour.
/Merf - Yes, no, maybe?
