Basically, the image format should be TF_TXD1 (for TF_8888 textures), the resolution for PWL is 1024x1024, and the format is .dds, right? And do the hero icons display correctly, or is there an issue with them too?
In Photoshop, when saving using the Nvidia plugin, there's an option to choose how many of these images there will be (I don't know how to do it with other programs: most likely, MIP is set to 0 copies by default, although I'm not sure). Also, in the config settings, in the game profiles, there is a value for MIP (zero is the most optimal option), but this is not so important.
