What "optional" features do you consider mandatory?

"Everyday we take the Massive daily posts and bring them to Dragoon discussions. We would like to thank Massively for their original content."

Whatever your preferred style of gaming within the MMO sphere, there are certain elements that were once seen as essential to the genre that just aren't as important any longer. Blaming World of Warcraft for eliminating a lot of the depth from online worlds may not be fair, but when the market leader doesn't bother with player housing or endgames that aren't gear grinds, it's not hard to see why other games have followed suit. And even that game boasts some features -- like altering character features post-creation -- that others have yet to adopt.

Appearance tabs, social mechanics, player housing, player transports that do more than just increase speed -- all of these elements are now considered to be highly optional. But are they? From open-world PvP to simple roleplaying amenities, we all have certain features that are treated as optional by designers but aren't optional to our tastes. So what features are generally seen as not necessary to a game that are necessary for you to even consider playing?
