Not sure if it's been discussed before but I couldn't see any reference about this.
I was looking through the files in Darthmod.pack and I found this interesting set of values:
In the _kv_rules file:
factor_attackdir_flankleft 25 (vanila = 8)
factor_attackdir_flankright 15 (vanila =8)
is there any specific reason why the value is different ?
