Every kind of graphics update is a little jarring at first, but man i got used to the new gralat look fast, and I like them so much better. I could never tell what the hell the old gralats were supposed to be. Now they actually look like something. Very, very good change (and I'm speaking as someone who generally doesn't like change).
But I'm not so crazy about people wanting all the graphics updated. I mean I fell in love with Graal Classic because of it's overwhelming similarity to LttP (graphics-wise). The old Facebook server had a nice look, but I wouldn't want to see the whole tileset changed. I like these occasional, once-in-a-while graphic updates.
