Is it better to use? (A.I)

I have multiple enemies, and I want the A.I to behave different, and I already have 1 enemy setup with the BB/BT.

Now should I make a new BB/BT for the other enemy or use the same one?

Hey there, it depends on the common things they have, if most if common then yeah try to group up, if they are mostly different then just create new BB/BT.
