I may have been lucky and unlucky.
Right now the accuracy system seem solid, i like it a lot.
There s only 2 things i noticed.
Aliens shots seems to bypass the shield in direct front shot too much. (ie they don t damage the shield and my soldier is wounded killed)
Pistol seem to have a range a bit too good compared to rifle. I would shorten the pistol range a bit.
Just 2 cents.
