+1 here, coming from Pirox.
HB is a different beast. It has its pros and cons vs. pirox and everyone has a preference. HB (for the most part) 'just works'. If you want customization, you are kinda left out in the cold, if you aren't a developer. For 90% of users, that's okay by them since they just want to click a button and run it.
When I first came over I was VERY confused about setting up the bot...because there wasn't really anything to setup. It literally just 'worked'.
As slook said, you do need a plugin to make it 'more powerful', but I think this cuts down on the bloat and footprint of the bot, allowing the devs to focus on core functionality (update/fix things faster) and letting others take the lead developing additional functionality. If it was more comprehensive, you'd have more down time between patches (see Pirox) and ppl would complain. So it's a catch 22.
It would be nice if there was a more comprehensive wiki to describe the preferred plugins to use for certain tasks and in an ideal world, each class would have an up to date CC for each spec (for both PvE and PvP)...but it is what it is.
I personally, won't (overly) complain, since i only had to pay a ONE time fee and the bot works for the majority of my needs. Expecting it to be Pirox or any other bot (and to work accordingly) is asking for disappointment. It has its place and its popularity speaks to that.
