I think that most regimental leaders would like to see melee fixed before you move onto other objectives. I don't know if we're being ignored, you don't care, or you don't know how... It'd be nice to know what the issue is with just fixing the melee. Is it too hard, is it not in your interest. Just curios.
There was 2 Melee Updates in 2018 and a Performance Update earlier this year I believe. All of these have been prerequisites to the next update which will have an impact on melee, as well as other things that is set to get into beta soon (hopefully)
AGS is not branding this update as exclusively a "Melee Update." Rather, a "Mechanic Improvement." Which will be a general improvement across the board on things such as player collisions, which are crucial for melee combat, but also other aspects of the game.
Little is known about the specifics of this update currently, but I'm glad that AGS is prioritizing it, as it's badly needed.
