I like the UD models of the units. Many effects not in yet like destroyed building explosion, spell effects like Lich frost nova etc but i know you will fix them in due time.
Now with the heroes i would like to see the male Death knight and i would like to know will there be an ingame option to turn off the gender swap for us oldschool players or not?
Dreadlord most important: i think his walking animation could be improved because he had a very characteristic animation ( similar issue like Blademaster ). As with the model itself i would like to see the Dreadlords ( default multiplayer model and other campaign Dreadlords) more armored up ( add the chest peace ) like Tichondrius and Mal ganis are because Dreadlord art in War3 depicts them that way.Even if the main concern is making them look different you can make the armor collor different like with Tichondrius model.
