I'd like the shore waves fixed first. Water color depth looks fine already. Now, reflection color could use some work and water surface shadows (from ships, shore trees, etc.) stronger and affected by ambient color.
Agreed wholeheartedly. In addition to "Attack Ground" I would like an "Attack Group" option that keeps your units attacking the enemy units you've selected within a radius, so that if they move around they're still targeted. "Attack Ground" would leave your troops shooting at an empty space if the enemy soldiers moved out of the area.
The only other option is to boost the pierce resistance of all melee troops, which will have unintended knock-on effects.
