It seems like Jagex are taking after games like Wow etc.. I quit a good few years ago but one of the reasons why i chose to play rs was the fact that it was different to games like Wow etc.
The game has been in decline for a while, and people have been saying it's dead for years. Personally I quit ~ a year a go, but I doubt that the game is 'finished' as you put it.
Yeah, not going to happen. People have been botting for years, no anti bot measure can effectively stop ALL bots, color bots and stuff will last no matter what.
I'd love to see anti goldfarming measures taken though.
