Not really sure if it's because we lack grass length or or something else but the rivers seem unnatural. I know we don't have many rivers in maps yet (course I don't fly around the larger maps so I'm not sure), but being that I fly WWI a lot I see them every flight and they just look "off".
My wish is for either taller grass around the rivers to add the effect that rivers aren't completely level with the top of the grass, or to add a little depth to the rivers such as a small incline into the water (maybe having Rivers sit at -1 feet with edges declining at 6" per 2" horizontal?). I have no clue how hard it is to code and it's not a big problem, but maybe when we get some sort of graphics change again it could be worked on if possible.
As for what I'm talking about to anyone who hasn't really looked at rivers:
What a river normally looks like (depending on where you go):
Can see the water sits lower then the trees/grass level.
Water is not at the same height as grass-top.
Maybe it's just because I live on a river that it bugs me, but it's just a small detail that sometime I'd like to see changed.
