The Daily Grind: What cool feature was still a disappointment?

Wintergrasp in WoW.

Keep Sieges in Warhammer.

The Abyss in Aion.

So much disappointment there.

No contest here for me: Eve's planetary interaction...

Nerfing Arcane Barrage in WoW's PVP so it couldn't be spammed as splash damage due to the reduction in its scaling. Man, I felt the pain that day.

The space combat of Star Trek Online, was just so......meh.

APB.... Just like... everything..

Flight in Aion

The limited flying in Aion.
The UI and mouse in FFXIV, (still in beta tho).
The first expansion in WoW (BC).

Death music in APB. I had loads of great samples lined up from cool songs before discovering that you had to create it yourself in the "music creator"...!

just like ssieth said, PI in eve was probably the biggest recent disappointment for me. It's just a useless minigame, and in all fairness there are tons more entertaining ones on the interwebz. fail fail fail

in wow there have been 2 different things...first of all, open world pvp (from tbc onwards) failed in a ball of flaming crap. and it's a shame, coz it can be done and is done (whining aside) with moderate to great success, usually becoming one of the central parts of the gameplay.

secondly, the dumbing down of just about everything in order to support the mentally handicapped and facebook gamers. it's always presented as a new feature that makes it more smooth and fun, but it ends up just making the game lose it's flavor. nowadays everyone has just about every skill. my mates just spam their respective aoe heal without even looking at the other health bars. hybrids are just as powerful as the pure classes in maybe 2 out of 3 of their roles. a warroir/dk/priest/drood/shammy/pala/ should never ever out dps a mages, rogue, huntard or lock, it's as simple as that. or a druid outtanking a warrior, it's absurd. but apparently classes don't matter, coz everyone's special.

oh yeah, just remembered something else...the multiplayer trading in Cities XL. great idea, but full of bugs and waaaaay to loosely controlled by the devs.

Something that was added, but way less cool than it was hoped to be (and could have been): Star Wars Galaxies' Chroniclers system. Was supposed to be a nice way for players to make quests for other players, but ended up being yet another grindfest and even a year later it doesn't have basic relics for several types of game play, i.e. entertainers and space. Another squandered opportunity for SWG to do something cool only to get it wrong in implementation.

Also, the entirety of Vanguard.

Everything about Aion. That game could have been #1.

It's funny you should mention this the day I let my City of Heroes subscription lapse again.

When she hyped the Alignment System, Bianco said that it had "over 160 missions" worth of content. What she didn't tell us is that that counts both endings for the tip missions, that the tip missions are rigorously sided, and that they're rigorously level-banded. Nor did she tell us that, for each alignment and level band, there is one and only one alignment mission that you have to repeat over and over again.

So the net effect is that the Alignment System amounts to "daily content" (you're encouraged to run it every 20 hours, by offering rewards that you have to repeat the whole series of 11 missions 120 times or more to earn them) that consists of roughly 10 missions per side and per level range, where you need to pick the same ending every time to keep your preferred alignment, and where you do 5 to 6 of those 10 missions every day. It couldn't possibly have gotten old any faster than it did.
