I'm going to take a realism standpoint on this topic here so here we go:
Customizable characters would be welcome given that different soldiers wear different gear based on need and looks (sometimes
) I would enjoy wearing special hats like a bandana, balaclava, patrol hat, standard helmet blah blah blah as well as choosing my body armor as perhaps a vest or a t-shirt (to show off the guns haha) or just standard bdu's. Even different camoflauge selections could be cool if they were different enough to warrant the choice but were still unified under the team color so that there is no confusion.Squad mates changing uniform to match yours is kind of awkward and from the realism standpoint, not compatible. To fix the issue of not knowing if your human ally has squadmates or not, maybe the same small circles that you see around your squad appear around the ally's squad but with a color matching that of the leader. That way, you can tell instantly who is under who's control.
Flags: Not a fan for a few reasons. Number 1, armies don't go about flying flags in the middle of battle
Number 2, there may not be buildings near a capture point, Number 3, the minimap already clearly denotes who the land belongs to.Emblems? only relevant if flags are implemented (which I highly doubt will be)
