To make it easier to level professions to 800, most recipes will stay orange for 20 more points. This is a huge change! For example, the blacksmithing 780-800 part needed around 120 Demonsteel Bar and 60 Blood of Sargeras at minimum to craft 30 Waistguard. (you probably needed to craft 50 if you were unlucky). But now you will only need 20 Demonsteel Bar and 10 Blood of Sargeras to craft 5 of them.
A lot of different types of addons are doing exactly the same thing. For example, Cross Realm Assist was an cross realm addon but in fact it is an LFG addon with its own UI. Serverhop and WQGF were doing exactly the same thing from program logic perspective. Even Badboy as a chat filter addon would filter LFG spamming. The idea behind BlockChinese could actually be used for premade groups as well. There is no point for people to install so many different addons for doing the exactly the same thing. These features should share the same code base and work together.
