I love HUD mods. Absolutely love them. And for me, it's what I like, not what's practical, or efficient, or even sensible. I wish I had my world of warcraft HUD modded up screenshot. It was a mess of information. The more info the better. EVERYWHERE.

However for a game where information is irrelevant (FPS) I want a minimalistic HUD. My L4D2 HUD is very minimal. I likes it that way.
