| The only way to combat spoiler sites is to interject some sort of randomness or just flat change/redesign them regularly. I'm not sure how much a developer would want to get into that tho.
It's much like boss encounters that run off scripts. Once you learn the scripts (and post them) a 6 year old could do many of them. Of course the more random you make encounters/quest the more people gripe they got the crappy one or the hard one etc.... |
