Yes, this is true but it would require a lot of man hours and lot of tweaking to get it right. It's not as simple as running a % based number reduction across the game like many people seem to think. If you read the tweets by GC, he already said how they plan on doing it. They are just going to give buffs to higher level people in old raids, which is a rather terrible concept in my eyes.

They keep making the game feel faker and faker, there's no surprise they keep losing subs. I don't want my character to be stronger in some areas, than weaker in others. This change will be the biggest sub loss for them, I am certain. They just can't seem to grasp that their main player base, casuals, do not want major changes.
What about the players that have been playing since launch, and keep playing for bigger numbers and the sense of getting stronger. A large chunk of the player base thinks this way and plays for personal character development. Now they go from doing big numbers to tiny numbers, and feel weaker. You cannot tell me that if they did something like this in Diablo 3 that the entire player base wouldn't freak out. Lots of players use numbers as a sense of strength, by lower these you piss off a lot of the fanbase.
There is nothing stopping people from upgrading their low end PCs. It's in the terms that the games requirements will raise overtime and it is up to the user to upgrade their computer. Big numbers play a very small part in the overall performance of the game, and would only make a large difference on people with very cheap and very old computers. Computers that should of been upgraded years ago. Why should the entire playerbase have to deal with a number squish because John wants to play on his $150 e-machine that he bought 8 years ago?
The argument goes both ways, by doing the number squish you will piss off a lot of people that have the "bigger numbers" mentality. This is a LARGE chunk of the player base. By not doing the number squish, you piss off the people who refuse to upgrade their incredibly out dated systems, or want to play on higher settings than they should be. The people who have the argument "I'm tired of seeing giant numbers" can be resolved with addons or a future patch that condenses numbers into better formatting, such as 100K, 100M, 100B, etc.
