In sparse forest areas, add patches of dense forest. This would make line of sight more varied and complex, facilitating player ambush tactics.
Hopefully, we can see a large number of such interesting forest patches (that provide tactical cover through line-of-sight blocking).
I don’t see much advantage in that.
Because the “sparse forests” already severely limit the view.
You really need to try it to experience the fun of such terrain. Hahaha.
