This is presumably what was specifically causing the WoW throttling from the article.
>>"We recently introduced a software modification to solve the problems our customers are experiencing with World of Warcraft. However, there have been recent changes to the game, which has created new problems. A second software modification to address these new issues will not be ready until June."
I'm not 100% sure, but iirc the "recent changes" had to do with WoW changing the TCP ack frequency when running, more than doubling or tripling the total number of packets sent over any given period of play time. They turned this on with a recent patch, but hotfixed it off temporarily because, as you said: "it quite negatively affects the network hardware". People with crappy routers/modems were apparently having problems staying connected.
