Hey brolly,
You're right, I owed you a follow up specifically about this - my apologies. I wrote in my follow-up post that we're going to be arranging a Q&A with members of the team with a upcoming update which will be an opportunity for you to ask the specific questions about new formations that you mention.
To some other points I've seen in the thread, I can't provide a concrete date yet for these changes, and I'm really sorry about that. I understand the frustration, as we let you guys know the changes that would be coming some weeks ago now, but I wanted to get you an idea of what we'd be working on with formations specifically right away.
When I get some concrete times on when you can expect that update, I'll provide ASAP.
