The game once was set up to use "full defensive" stance as auto-defense.
It had to be changed for a good reason.
What is the mysterious good reason? ;P
I'm not sure why autodefence was so flawed.
The reporting part is interesting
As i understand, the auto attack is for players who crashed, but their chars are still in game for a longer while. Long enough that auto defence wont do the job, as even in full defence the HP will drop too fast and it is better to kill attacked before it kill the character of crashed player. Althhough i think the server should realize fast enough so that auto defence would be just fine. More, the auto defence should be only for max 30sec, to avoid cheating in training LA for example.
To the point. If you are seeing someone who is fighting, but not responding to your calls, there are 3 options:
1) he is in guild tab and is annoyed by the damn flashing tabs, in bad mood and even if he would care, he is temporary sick of people opening their mouth in his vicinity

2) he crashed! yay! Good that even if this feature is helpfull in the 1%~9% of meant way, we are thankful the we aren't doomed for DR.
3) he is cheating! Oh no! how can we know that? what if he is 1) or 2) and we are wrong? We are gonna report him and GM start with ban warnings (which appear in the center of the screen and cant be missed) just when the guy will be afk for 2min doing a tea? The rats will be coming from all directions and the character will kill them all automaticaly for the cursed 2 minutes when he didn't even want to kill a thing, but make a tea! Additionally, when he came back with tea, he got even more annoyed seing that PS crashed again! "Enough, maybe i play tommorow" But tommorow he can't join, coz he is banned.
Who knows, maybe this quest for ban cure

will be actually more interesting than rat killing, but i'm not sure if I would enjoy it.
And remember, always look on the bright side of death.... erm, i meant life, which means to not get unnecessary irritated after reading this post ;P
EDIT Craconil, when you are cheating laying poker, are you cheating, or are you not? You are allowed by the physics mehanics and everything what this world allow you to do, so is it a proof that it is not cheating? Like you didn't gave any proof or "why" in your post.
