One of the things I love about Tolkien is how mythologically epic the battles are: Apparently, the elves and Numenoreans spent two whole years preparing for the War of the Last Alliance, then spent a decade fighting their way into and besieging Mordor. Of course, this was but a skirmish compared to the battles in Silmarillion, which would literally change the landscape of the continents.
Nice vid, you showcased the changes very good. Finally a real lotr battle map and not that green grass 101. They killed the colour and lighting, looks just like the movies. Hopefully they are able to change the UI in the future.
