I have to agree with Aramara and Mishka: I like the old walking speed better... The slower walking speed makes the game a tad less playable, in that it takes longer to get somewhere by strolling. And the animation seems less natural now too (Or maybe it's the same animation, but just seems different). Timil, a ylian, seems to march stiffly now instead of the natural looking stroll he had previously. Perhaps it IS a 'feature', but features are up for the same type of scrutiny as bugs, especially as they relate to player satisfaction.
Another bug for me was that after installing (and making sure my video card drivers were up to date), both cities of Hydlaa and Ojaveda had no textures showing, and I'm not sure if the shaders were working right either. Timil and NPCs looked like they were covered in TV static patterns.
I like some of the other features though, especially the waterspouts in Hydlaa fountain! Nice touch!

And it's nice to see the menu tabs/buttons have been changed so that only the selected button has that yellow line indicating that it's active. Much better!

I uninstalled my client and tried downloading the 5.9 torrent. When that finished and I clicked on the installer, it just froze up without starting. So I tried downloading from one of the Redlam mirrors. Got a 404 page. So I tried downloading the installer from one of the german mirrors. However, the file extension says .run instead of .exe, and when I change it to .exe, it gives me an error saying it might be fore 32bit windows. (I had downloaded the file that said 64bit.) So...... I guess I'll keep trying. Maybe I'll reinstall my old client and let it try to auto-update again.
