To echo this, all of the weapons have a different "dpi" when scoped in... and it's definitely not the same when you have an attachment on it.
Longbow is a great example of this...
And compare the movement of the wingman vs the longbow... the same "flick" doesn't work for both weapon's iron sights...
I'd like to add physically accurate targets as well... the head hitboxes on the existing ones are much too large...
Also give us some fast moving targets as well. (random movement ones would be great as well...but not holding my breath on this one.
and for god's sake, give us the option to skp the BS at the beginning!
Give us a way to take damage as well to practice other techniques.
