I believe each component has its strengths and that they create the most intelligent and responsive AI together. After creating AI without Behavior Tree, you start to wonder whether it's truly necessary to use. The problem dictates the solution, and when you use one solution for every problem, you don't solve anything. I find that using the strengths of Behavior Tree and other components to fill in the weakness results in the most promising behavior.

The pros and cons of using Behavior Tree

The following are the pros:

It is easily extensible
It syncs the Blackboard instances

The following are the cons:

The design dictates the execution flow
Setup is required
