- and 3) seem to have been fixed but not 2).
Under water wreckage is much harder to see than it used to be. This makes the game worse not better. Players should be able to get the reward of reclaiming wreckage. While a player is trying to scout, fight enemy units, maintain/develop their base, etc the last thing they need is difficulty seeing the wreckage they are trying to reclaim.
Turning 'reclaim labels' on can help to see wreckage however in general this presents a bewildering volume of green numbers onto the screen that undermines visibility of units and is very distracting.
There should be clear easily visible contrast between black wreckage and the blue of the water so players can see where to direct their engineers to reclaim.
I think it would help a lot if this was fixed.
