If Blizzard “improved” upon the background technology of the AH to potentially increase its functionality and response time, there is a chance that TSM doing what it’s been doing for years with low impact calls from the player could be leading up to bottlenechs due to the amount of potential calls across the entire gaming community. Especially if its become more widely known, and more and more players start to use it.
As i stated above, it is probably fine on the micro-scale. But when its becoming macro-scale… not so much.
Edit: It’s just like when a something awesome is coming out, like a collectors edition that is only available on one site and is launching at a certain time. The amount of what are normally considered low impact calls of just getting to that website can overwhelm it simply due to the amount.
