A person intending to use grass as cover is more likely to obscure his own vision than his own visibility. It is only pretty, very pretty at this point, but not functional.
These two pictures show the same cluster of trees from different perspectives. A person hiding behind these trees may think he is covered, when in fact he is wide out in the open.
You can observe anywhere in game that grass does not render beyond a certain distance which is not actually very far.
I know that many people are aware of this issue, and have been for a long time. But I don't think that makes it any less relevant. With beta approaching fast, I'm beginning to worry that this may never be seriously addressed. It is quite literally broken at this point, and with the recent change to grass not addressing this issue, I am even more concerned.
If there are plans to render grass further in the future, I apologize for my ignorance. I am aware also that server owners may be able to set grass render distances themselves, which would make this issue mostly irrelevant. But this is concerning enough that I am compelled to post about it. I think the new grass is fantastic. It would be a tragedy to see it not utilized to it's full potential.
