[World of Warcraft]Whose genius idea was it to put portals directly to Blasted Lands into every Capital City?

Who exactly decides that the risk of these portals ever malfunctioning within the heart of your city, which other side is right next to a rather large gate that has stampeding demons fighting into the world of Azeroth, outweighs the convenience of porting to the Blasted Lands. 

Even if it is to boost your numbers defending the gate in the first place, wouldn't it be far easier and risk free to just gradually muster numbers the traditional way of flying/mounted/vehicles etc.

It seems like demons have made it into the Blasted Lands in the first place anyway, and they already seem contained with the few out-holds Horde and Alliance have there.

and exactly what is preventing that portal becoming two ways, who is maintaining the portal for those 24/7 hours 365 days a year?

The portals provide swift transportation for our officers and other important personnel, as well as to ensure a quick flow of information. Should our outposts in Outland fall, or even just the defenses around the Dark Portal, we need to know about it immediately. 

They are constantly maintained by rotating mages, some of which are still novices and are sent there for seasoning. The Blasted Lands provide both an opportunity for practice as well as gaining experience with demonic entities. Invaluable lessons for every mage. However if the portal sites are ever in danger of falling into enemy hands the mages can sever the connection instantly.
