Incoherent rant before going to sleep perhaps, maybe not. But you asked feedback. Well, there it is. I'm not sure what to think. Maybe there's an idea of providing feedback in your vids which zones need density buffs and putting a link to that on the official forums.

although I do agree with you Kamisei- the more these runs are made aware to blizzard, the better the game will eventually be. i strongly disagree with you that videos like this are detrimental to the community though. I don't think you can be farther from the truth on that point.
Of course there is many different ways players play the game. Some enjoy messing around in random zones, others prefer one zone or act over another, while others- such as myself, enjoy discovering new ways of optimizing exp. And of course, it is always good for the game to bring out the exploits so blizzard can correct them.
