What you also need to remember is the majority of the HB crew are based in Europe. They can't test anything on live servers until the patch occurs in Europe. Those on US servers will have several hours of bot downtime before the HB devs can even think about testing.
however the patch occured in europe almost 20 hours ago too. the problem is, if any other software, product, business - whatever you're paying for, let's just say WoW (replace it with any other successful product), would be down for 20 hours now, EVERY ONE would be ranting. HB is a registered business too, and they obviously don't mind to be a "growing" business, but they obviously don't adjust their service to that "growing" business. it's pretty simple; people are buying a product, people expect a working product. this holds true for every friggin product in the world, HB is no exception (why would it be?). The only difference between HB and every other growing, professional, successful service can be seen exactly here, in the forums. communication between provider and customer is extremely poor, service does in no way adjust to the growing customer base, people who are paying for a product and are (of course) demanding for a quick update, are getting bitched in forums by other kiddo customers who love to lick the dev's lollipops. the whole thing here is stuck and definitely not going in anything like a professional direction, it's simply the opposite, it feels like a friggin kiddos birthday anytime you open the forums, and this holds true for ANY represented side here, including the provider of our product of choice.
fact is, WoW is more than 7 years old, and the only reason for a LOT of people to stick to that game (at least partially) is HB. This is a train the developers of HB could hop and jump on, and really make a LOT out of this situation, but they obviously want to keep it running as it is, with less than a semi-professional service. I realize, if HB is down again and again, that I probably don't need WoW at all anymore, therefor don't need HB anymore, and start caring less and less about all of that. this is just sad, since HB could (as mentioned above) really make a lot out of the current WoW situation, before this game will really and finally die off during the coming one or two years.
