I personally try to avoid addressing posts concerning "do this, do that, here's why" from customers. (I do take such posts seriously, I just try to avoid replying to them, as it causes the "band wagon" effect to occur, which is never a good thing.)
The reason we even started working on the new UI when we did, is because HB was at a point where it was stable, with very very few reported bugs. (The EOTS starting issue has been on the back burner; as it really only makes you look like just another itchy retard at the start of a BG. I believe I just fixed it now however, have to wait on the next queue to actually find out though, so take this claim with a grain of salt.)
IB will be seeing quite an overhaul in the upcoming weeks, so not much I can say about it at this time.
Questing relies heavily on profiles. While usually 'bad profiles' get put on the bot itself, in most cases its the fault of the profile writer. I'm not trying to pass the blame, there are some bugs, and inherent flaws in the way HB handles questing. The bugs that are actually in the bot itself (and not in the profile) are actively fixed as we find them, or are informed about them. Also, when it comes to questing, Blizzard has one of the widest assortments of quests of any game. This also means, HB has to handle all those different quests. While its impossible for us to deal with every single quest type, and every little special mechanic, we do provide a way to handle them yourselves, and we're always willing to assist with custom behaviors, etc, if need be. (Though, we do need a toon to test it on, and all the other requirements to ensure it works properly. Often we have people asking us to write a custom behavior to complete some obscure quest, that requires us to level a toon to some random level, complete a fairly long quest chain, and then hope we can even write the behavior for it. Worse still, are quests that are class specific. This obviously isn't a very good use of our time.)
I'm not trying to beat back your opinion, but we do have a method to our madness! I swear!
Lastly; we're looking into an auto-updater, once we can decide on how we want to go about it at least. (No, we don't need ideas from people, we're grown up enough to decide how to do it ourselves!)
