Okay so this one is admittedly a hot potato of sorts. Obviously there has been a lot of heat over the Mk3 vs Mk4 discussion on other platforms and there is a non-zero chance of those sorts of discussions flaring up here as well unless the policy is “don’t discuss Mk3”. I do think that there are going to be players who either still prefer Mk3 or play both in parallel or are playing Mk3 until they find a Mk4 Army they really like and I do think it is worth allowing some discussion of that here, at least at first. If it becomes impossible for there to be a thread about Mk3 without it devolving than you would have to reconsider, but I think the optics of disallowing or actively discouraging it from the get-go would be pretty bad. If it has it’s own tag/topic/subcategory (still trying to get a feel for the terminology of Discourse) it may be containable enough to just let it be?
I’ll admit I don’t really know what the right answer is here. Personally I do still intend to play Mk3 occasionally and would like an official place to have discussions about it, but I honestly don’t know if it would just completely blow up in PP’s face.
