Regarding Discord vs the forums here, I think part of it is that Discord also has mobile clients available that can make it easier to keep tabs on while you're away from the PC or PS4, or if you're a PS4 player, you can have it going on a smartphone or tablet while you're playing on the console. It's a bit more convenient that way. It is possible to read the forums on a smartphone, but you'd have to flip the screen to landscape and zoom in a bit to make it readable.
However, I see the two as filling two different needs, as others have pointed out. The forums here are great for lore dumps and much more detailed discussions. The Mateus Discord, on the other hand, is a much more free-wheeling on-the-fly chat that can bounce from topic to topic. On the other hand, I do see more Mateus event postings there than I do here, and that's a bit unfortunate.
