True enough, I'll post my reasons here:
The explanation of BAB in the class description is for those players whos' DM's choose to interpret the BAB as stacking for purposes of total, but not for purpose of number of attacks. I have had some that go let us say you have fighter 6, and paladin 10: you get two attacks, rather than three at :+16/+6
+10/+5 from paladin, and +6/+1 from fighter, whereas by normal rules this would be +16/+6/+1, or +16/+11/+6/+1. due to total BAB.
