While in essence I agree with the conceit that shipside roles should stay shipside, the bulk of shipside activity is locked to the first and final half-hour of a round (assuming a hijack) in the current game. Unless someone really sexy comes-up with a way to shift that a bit, some degree of groundside work shouldn’t be frowned upon.
Part of this idea was actually inspired by some of the variation in strategy that groundside Surgeon and static comms brought-on: pushing marines from simply barricading the LZ and historical points like Hydro, and pushing them into different kinds of supply lines and strategy. While I don’t think that the pursuit of a minor buff would seriously shift marine cading strategies, kitchens are usually in a great place!
Sorokyne and LV have kitchens within sight of an LZ, whereas Kutjevo and Solaris have kitchens at some of their most prominent marine FOBs. I could see these as a great way to not just include more dynamic play for the Mess Technician, but also as a more engaging strategy for marines: A hearty stew won’t repair your bones as efficiently or fast as a surgeon would, but you could remain awake and active while standing guard or RPing with other marines as the food does it’s work - further ensuring that there are bodies around these points who can still actively play and contribute to the round.
