Keep in mind, Jamba is an addon designed to help with the multiboxing aspect of the game, not an all-in-one addon Comp. The more stuff you add to it, the more you run into bugs and conflicts with other addons.

And the more bloated it becomes, the less people want to deal with configuring any of it. I was in the process of writing a more tutorial-style guide for Jamba before WoD and it was a seriously intimidating amount of documentation, especially for people who are already dealing for information overload on how to multibox and set up their chosen software and teams. By the time someone is getting into Jamba, they don't want to spend a whole day configuring dozens of modules to do stuff that they don't really understand.
