I mean, we have Gameplay, Q&A, Ask an Imm which are all largely indistinguishable. Plus, almost every Imm has their own forum.

Realistically, we could probably due with half as many forums just fine.

But I can see the argument if they want to keep such discussions easily available for people to browse long after the thread is active, that would make sense. But the way the game always changes, it seems like information can become obsolete pretty quick.
