I'm angry - I've worked on a texure for several hours and I use GIMP and when I saved it, today when I came to use it noticed some pink and green pixel parts among the texture that look just the same as whenever you do a 24 Bitmap and save it to 256 color... well not that bad but some parts of the texture don't look that good anymore - all that because the plugin of GIMP When saving I use Compression BC1/DXT1... something like that was the name so that a 1024x1024 doesn't become 4MB if uncompressed so this turns it into some crappy quality size 512KB.
Any way to save them to lower size without any noticeable difference in the quality? This texture is ruined... well to some extent it is, I don't keep a copy.
Idk what compression Blizzard uses if any but im sure Photoshop can save DDS better!
@Eimtr: Go ALWAYS save a copy man! I use photoshop and I use DXT5 without any visible loss. I used 8.8.8.8 before but filesize is huge in comparison and quality isn't that better to make it worth all the filesize.
OK I saw a 1024x1024 that screwed up the quality of my texture that was 4MB with BC1/DXT1 became 512KB, with BC3/DXT5 became 1MB. I guess I can do some replacing and saving that as DXT5, thanks... will try to improve the damaged parts of the texture.
I made some tests with a 2048x1456 loading screen and file size for DXT5 is doubled in comparison to DXT1. Quality isn't visibly different, but I believe your issue is with mip maps. Probably DXT5 handles it better.
Some info, it seemd DXT5 is the best option. Tested with 1024x1024 texture 4.00 MB.

DXT1: Removes any gradual alpha you may have added also greatly reduces the quality adding random color spills of dark green or red almost as if you made it 256 color, also lots of the texture details become blurry, adds random pixels of existing colors. Worst quality! Saves the most space - the 4.00 MB is down to 512 KB that is 13% of the original Texture's space.
DXT3: Removes any gradual alpha you may have added also reduces quality. Some dark red color could be added as a result of the quality reduction also slight blurriness or sharpness but no random pixels or color spills unlike the DXT1. Becomes 25% of the original Texture's space. The 4.00 MB is down to 1.00 MB.

Good luck.

Thanks, gimp has DXT5 so I will save it.

Conclusion: Use BC3 / DXT5
I would also recommend using Paint.net
