"Hey, MMO support staff, your game is suddenly not working for me because it does >blah<. It only lets me surpass this on specific low-level characters."
"Hm. It sounds like you have a dual monitor setup. You need to make sure your monitors have the same resolution and tweak the graphics settings a bit."

nice to know that AAA support staff doesn't need to read my entire e-mail to give me a bad solution.
