Discord is better for real time conversations and immediate postings so yes myself and Champ are in there more often and it is overall more active than the forums are.
I looked just now, Nico posted after his chat session last night (for me), there was then a 12 hour gap with nothing and 9 posts since that with the only subject being how someone says good morning.
No questions (so obviously no answers), no discussion about the faults in the showdown etc. In my experience, if you did go there and raise that (the showdown) and ask why G & A faults were being fixed first my guess at the answer (if any) "G&A affects more people" or something like that. Any further questioning along the lines of how long the showdown has been broken would be met with "G&A is getting fixed first that's just the way it is".
Three of the posts are from wgt staff too. I couldn't count how many posts have been on here in the same time. Here we've had players asking questions and other players giving help. We've discussed what's wrong in the Showdown and messed about too. I think there have been nine active threads.
I really don't think Discord is more active than here, lol especially if you take out Nico and Champ's posts from both.
