We understand all but like i said before , there are players which are noobs and will farm in woods even they are not mad at all.And there are players who are ragers who play and farm only , it is his choice , he is will lose that game as much as you will.If he stays in wood , he is gaining exp and gold for it , he can do it on lane as well ,but he is safer in woods.If he doesn't want to join team fights , it is his choice , we cant do anything for it.That would be like we ban people for being noobs , even you see it as being afk , but afk means AWAY FROM KEYBOARD , and surely he is not doing that.
And even we make that rule , it would be very undefined which will cause moderators trouble , because people will surely spam forum with questions like : Omg i cant beleive he did not ban player for that blah blah.I know players hate when moderator declines their ban report just because moderator sees it other way.
And i mentioned that this rule will make reports ages to be solved and it brings nothing compared on time used to solve it , and best thing of all , it might get denied because if we add that rule , dosens of players would report any player who farms longer than 5 mins in wood and still Ban Unban mod would have to look at the whole replay for what ? Some rager is mad because someone stayed out of few team fights (still he will not mention that in report , he will say "Retard mirana never came gank , he just farms )
So we are definetly not adding that rule to be considered as game ruin or afk.If someone suggests better way to deal with this problem , staff will look into it .
