In the UK sub price has been £8.99 since the game released in 2005... With inflation that means the cost of the sub has actually been going down continuously since release. I don't like paying more for something any more than anyone else but the price of everything else has gone up in the last 10 years so why wouldn't WOW ? It's amazing they kept the price the same for almost a decade...
Increasing the sub does nothing more than bring it back to what we were actually paying in 2005 with inflation taken into consideration.
