After eight years, we've had ample time to grow weary of the ugliest graphical glitches that persist in the game. The old character models get cited for a variety of abuses. Night elf hands/mittens, anyone? Creepy. Sometimes, it's their expressions -– the terrifying rictus on a female night elf when she's "smiling." Just look at that screenshot up there. Definitely zombie material. And I know this isn't a superficial issue, because I swim. Ever looked up the skirt of a robe-wearing class while they're swimming? You can see their brains.
Blizzard's deft art direction and over-the-top, cartoon-ish fantasy aesthetic smooths over a multitude of aging and sins, but at some point, rough edges simply refuse to stay hidden. What do you find to be the most appalling graphical eyesore in today's WoW? Is it part of the older character models or landscapes and dungeon textures? Is there some aspect of WoW's graphics that shouts "old and tired" every time you see it?
