As I understand it, when deciding to use the HW2 engine GBX (indirectly) decided to accept the loss of formations but allowing them the use of the better engine. It was a marketing decision made on a game they didn’t know for sure would sell well and the community backlash has caused them to change their minds and fix it. They couldn’t have known pre-release and it took a while for enough people to complain for them to see it’s worth fixing.
Besides which, on the implementation side I can see that from a technical perspective (I’m a developer though not for games) trying to control the combination of squadrons which move, with individual fighters which move, all of which have specific locations and guiding AI is not a trivial task that can be completed, tested and released within a month without being a buggy mess.
However, getting back onto the topic of MP, if I’m right (I hope so) they have decided to release one big patch to fix a lot of the game issues/complaints including the MP beta, not just formations. This means we get the individual fixes slower, but is more efficient for the developers as it means only one batch of testing, bug-fixing and releasing.
And much as I’m still admitting it’s been a long time for this patch, I understand that in the meantime GBX has been busy releasing HW DoK, likely taking developers away from HWR to work on what has turned out to be, in my opinion, a very good member of the francise.
I think they’ve overall made reasonable decisions, other than being a bit slow/cryptic on the updates progress, and much as it’s been a year since HWR was released, if the patch is as good as it sounds then I’ll be playing HWR for another 10 years (like HW original) and that year will be a rather small blip in the long run.
