CHB1

/chotbar change 2
CHB2
/ac "Savage Blade"
/chotbar change 3
CHB3
/ac "Rage of Halone"
/chotbar change 1
Using the above macros on CHBs 1-3, all on the same CHB slot, you effectively make all 3 skills in chain under the same button. As for all the other slots, they can be identical across all CHBs, giving the appearance of being static.
The question/suggestion would only remove the 8 chotbar cap, and implement a100 user macro cap, and free up a lot of hotbars.
