IKR? The problem is exacerbated beyond belief in WoW, because Blood Elves also happen to be the prettiest race in the game.
Naturally, everyone then plays them because they want to look good. The result is eighteen-year-old knife-ears with no concept of their own lore walking around chewing bubblegum, adjusting their sunglasses (this is in a fantasy setting, remember) and threatening to hit people with a sword too big for them to hold.
Also, those chaps who feel the need to smash the laws of physics into itty bitty pieces.
Have you ever seen an anorexic elf holding a gigantic self-reloading rifle with a bayonet and a huge revolver-style ammunition thingy in one hand and a claymore as wide and long as her body in the other? It's not good for your mental health. -.-
