I would like to suggest updating certain strats(e.g. Naval Commander and Sky Menace) to reflect the World Map 2.0. It would be nice if those units could be affected by the strats you'd expect would give them buffs, especially since the goal is to make the map the new default map.
The only downside would be that this could impact custom maps. This may require either rewriting how strats work(e.g. disabling the changes to strats in custom maps by default, requiring mapmakers to enable them by hand if they want them in preexisting maps) or going through the database and renaming all custom units' types that fall into the updated strats' new domain(e.g. all "naval: defense" units could be changed to "naval: defence", allowing mapmakers to choose to make the needed changes later if they so desire, without making any major changes to how strats work. This should be a much easier way to fix the issue).
I suggest this because I'm pretty sure that some custom maps(especially those owned by inactive players) would be broken if NC players, for example, had buffs to naval: defense or secondary attack ships.
If this sounds like a good idea to you, I wrote a highly detailed forum post called "Change Naval Commander(and maybe other strats) to reflect World Map2.0" a while ago that details several ways NC can be updated. I think that my suggestions are close to the best ways to update NC specifically, and similar work can be done on the other strats that would seem to need the changes(e.g. maybe RA needs nerfs to naval: defense, and maybe GW should have cheaper but weaker corvettes).
I also go over how strats on custom maps would benefit from some customizability(though that would likely be a very large project), as well as some recommended changes to how the various ships work.
