It really annoys me that when I attack said creature, even though I am hitting the creature I still miss.
Is the hard coded into the engine, or is there a way of fixing/lessening the effect.
Major changes to the way the game works, like this, are rather hard to do. Combat Enhanced works for melee combat (the same person made Blocking Enhanced, also on PES) but not Marksman, they did try but ran into engine limitations.
You could try http://www.gamesas.com/bgsforums/index.php?showtopic=1032302&hl= by Casey Tucker, it's a beta, it may not do what you want and the download link may not work. Apart from that, should be fine
@ everyone else: Let's not have another one of http://www.gamesas.com/bgsforums/index.php?showtopic=1025807, they leave a bad taste in my mouth.
