Uh, for one, no mod would want to get that many PMs from people posting a thread about battles. Nor do I think any normal member would want to deal with that.
That's a horrible idea for one. None of the staff want to have to constantly run back to a thread to change something. I should know, since I deal with the song claims thread. That gets really old and tiresome easily.
I think the moderators of that area are glad clans are closed and want it to stay that way. >:
There doesn't need to be a mass thread for them, since people can simply scroll page to page to find a thread. And if they're that lazy that they can't search through a couple pages, then they don't deserve to find the thread they want. :x~
This person has tried to help, so I don't think that he/she deserves that, but you are quite true on your other points.
It would be too tedious for mods to keep control of the list, and it's just alot easier to search through the threads, usually taking less time than actually going to this proposed thread to find a link. Nice thought, but it wouldn't be very effective.
