Ok, i've seen a model change on the forums where Tirisfal and lordaeron are changed to pre-scourge invasion. However these are incomplete.
The Lordaeron grass is still dark, the trees are still dieing etc. Also the sky still looks plagued.
I don't know how to terrain edit, but what i would love, and i'm am sure many others would too, is a complete lordaeron revamp.
Elwynn sky, Elwynn houses, Undead ---> human, darkhounds ---> wolves, Zombies ----> bandits, skeletons ------> scarlet crusader models.
The best trees would be the pine trees from azuremyst isle or the pines from azshara.
The signposts could be changed, and also the lamps.
The starting area entrance 9the wooden pallisade) could be the human wall from elwynn.
The ganranary at The manor should also look fresher.
The ruined human towers should be normal human towers.
the metal fences should be low stone walls or wooden fences.
However the biggest change would be to Lordaeron itself.
Now this is not a terrain change, this a building, and so it would need a frame change, to get rid of the rubble, and chips in the outside of it. It should look regal and alive, like stormwind. The stone should be white, the lamps should be lit, the bell tower repaired,everything looking smart and like a working city.
I would do anything for this change ;o
