i remember in classic it hard capped at 3bo , but the other day while on a barb i was a holding a cta and it still said 5bo. it didnt show 3 like it used to. is that so ppl dont accidently screw themselves selling a 6bo thinking its a 3 and it still hard caps at 3?
Think of it this way, 2x +3 Warcries weapons on switch = +6 Battle Orders etc.
As mentioned before, CtA + +3 Warcries weapon is better because of the +1 All Skills.
It is up to you to choose.
