UI lag is the biggest problem with the game. It shouldn't take 3 seconds for an ability to go off, after you hit the button. It shouldn't take 10-15 second to switch gear and class. Everything takes too long. If the gear switch macro needs to lag to recalculate, it should only do that once, when the macro is created or edited. It should not lag everytime it's executed.

The problem is lag saps all the fun out of the game. Even if amazing content is added in the future, the slow UI and lag will render those efforts futile. I don't believe anyone wants to play a game that feels like you're playing it on old outdated equipment, and especially if you're paid good money to upgrade your system to state of the art.

BTW, since I've started playing again, the patches and updates have been tremendous. We're all hoping the game suceeds.
