A classsic-style RTS achieve a balance of this in Battle for Middle Earth II. Ships did not turn on a dime, but movement wasn't 100% realistic. I think with ship movement, 0 A.D. pklayers just want something better than what is currently in the game. The ship movement in the game right now is just too clunky. And so many people keep making formations out to be more complex than they need to be. Simple powerful formations can work. It has been done, except there were no bonuses in BfME2. 0 A.D. would innovate on that. Formations can be streamline and reduced in number. Battle Line is standard for infantry and ranged units. Wedge is standard for melee cavalry. Column is automatic. Then use modifying buttons: Open Order, Close Order, Locked Shields (this is the phalanx). I do like your idea of making bigger maps and making exploring more important. Settling up forward bases or finding good spots for cities would be more important. And yeah, using a 'column' formation to speed up getting troops across the map would be more relevant. I think a separate git would be needed to test thing like this. More resources is intriquing, but maybe keep the same resources and make different ways of getting them, like large open pit metal or stone mines that can be captured.
