Star Wars Galaxies and the NGE.
After losing thousands of subs to the Combat Upgrade (which in reality wasn't that bad and did bring a new sense of balance to the game) they decided tearing the combat, leveling, and overall gameplay system down to the ground and going with something new (that the SWG player base shot down at every turn) that was more "Star Warsy and Iconic" was the way to go.
Biggest blunder of 2005 and arguably one of the biggest in the MMO side of the gaming industry ever.
