Any type of software development of this magnitude usually comes with a work plan of some kind, and especially working from home they have to have some kind of internal document to know who is working on what and when they can be expected to be done with that.
Now I am not asking that they share that with us, that would be insane, but a general roadmap would be much appreciated and it would make reporting relevant bugs easier. Devs wouldn't really need to give anything to Callum, the outline you are talking of is already there (unless they are just letting everyone work on random things with no supervision, in which case we are all doomed

but I somehow doubt that is the case).
And yes I don't think that devs coming to answer in individual threads is a very efficient use of their time, it's part of why I am asking for this (it's awesome that they do that, don't get me wrong, but it's not their job). It's also really not uncommon to do this for EA titles.
