I don't know why, but seeing this kind of post pleased me.
Perhaps it's because my mind is graphically inclined as a designer and I notice the little things like that. I foresee this bothering me as well.
Thanks for the positive response! It looks like they're using a NARROW font variant of the base font to which we've grown accustomed. As a reault, the smaller font sizes with the black outlines now look really really bad.
Some of the color combinations before (like the dark purple chat text for Artifact quality items) were pushing illegible, but now it has gotten eyestraining and downright painful to try to read.
If I have to bump up a font size 1-3 points to restore readability, that's not much of an upgrade to the UI overall.
