For me, it comes down to how I organize my bars.

I separate the actions on my bars with an empty space.

1-3 Standard attacks
4 empty
5-8 weaponskills
9 empty
0 Featerfoot

11-14 self buffs
15 empty
16-19 situational
20 Empty

21-23 single target taunts
24 empty
25-28 aoe taunts
29-30 empty


New system does not allow this because my bars will have actions I can not remove.
