This is mostly correct, however, they can give their opinions about how dragons fly, etc.
Generally, if anything is incorrect info-wise there are a few reasons for that:
- The info was changed after the season deck was prepared
- The info was changed while the livestream was happening (this happens!)
- There was an inappropriately maintained info document
None of those things would really be able to be corrected by GPF members because those are issues with internal communication/documentation/processes. Although they may be aware of spell parameter issues being written incorrectly.
Just to give people an idea about how stream and blog info comes to be - there are a few different teams that are working on designing the game - including the parameters, season structure, economy, dragon spells, riders info, art, QA, backend tech, events - and they all keep things updated in various places. I go to those places after asking everyone if the info is updated - and pull that data for the blog and livestreams.
That data collection/content creation happens at timestamp X, and I do that usually a week or so ahead of time. Now - things are not always done by the time I gather information - so I often have to double and triple check with all of those teams to make sure the data is accurate, and even then sometimes things are still changing - so depending on who I ask, I might be told I’m grabbing up-to-date information but the person informing me isn’t aware of an incoming change - it’s pretty complicated especially since we’re not all in the same place (COVID protocol).
