This whole forum is not a productive use of my energy but it's still very enjoyable. And you seem to be here a lot too
Whenever I have a complaint/suggestion/request for a mod, I track down the mod author, and reply to their suggestion/complaint thread/system. And to take your argument to the logical conclusion, all of life is not a productive use of your energy because you are going to die someday/humanity is going to die someday/the universe is going to [likely] end someday.
That is, of course, silliness. We are doing things to resolve the death issue, as well as safeguarding the future of humanity. And we can only wait and see what tricks we can work out regarding the [possible] death of the universe. That's because, instead of just replying to the post of someone saying that the universe is going to die, we put energy towards resolving that situation.
Have you told the author of MystCraft about your feelings in regards to him removing the link modifier? If not, you should. I'd really enjoy seeing that conversation.
