Perhaps you have missed some points then. As I have repeatedly stated, I would like to know what is going to happen to the draw that was originally to have been a PK or Explosion chit. I don't think its too much to ask.
You may not like the idea of the PK or the explosion possibility, but exist it did, remember please that the Red Baron was brought down with a PK chit, so the historical precedent is there and to render pilots and fuel tanks invulverable to damage is a GROSS over simplification. The elimination of such lucky hits (I prefer the term, CRITICAL hits) is going to lead to a simple counting of boxes when deciding on a course of action.
I can understand that perhaps you like the idea of being invincible, most arcade games have that as an option and it does do the vanity good to crush your enemies, to see them driven before you and to hear the lamentation of their women.
As for myself, I don't mind the occassional reminder that I am indeed a mortal and subject to mortal weaknesses.
I tend to agree with SM & T on this modification. I just don't see thr point of it as an enhancement of the game. In many scenarios that are already 'unbalanced' by the planes available, this option just takes away one of the few ways the weaker plane to knock out the better one.

I don't think my or Tornade's arguments are overly extreme, though perhaps they are not in tune with your thoughts. I don't appreciate to be labeled as an extremist simply because I do not share your enthusiasm for a profound change in the rules of a classic game. But maybe my view is just another extreme one.
