these casters are horrible. whoever is controlling the hud keeps spectating not the optimal player and not where the action is. Also they keep showing the scoreboard for half a second wtf.
although this may not be ideal production, you have to realize that there are 2 people, one who is producing and casting, and another who is casting/observing. this is multitasking to the highest level, so although it sucks, lets cut em some slack
Not sure what you were watching... considering the wide scope and sheer amount of matches being handled at the same time, i would say they are doing extremely well. Especially when they are adjusting things on the fly and training people remotely with the gfx packages/implementation.
