I am unsure whether I am supportive on having different combat bars in general, but reading through this topic gave me the following ideas:
Say I have a few combat action bars focusing on different things, like fire, or ice, or healing, etc.
Suddenly, I find myself in an unexpected combat situation. Before I use any skill, I am allowed to switch between my different presets for free, but once I use a skill, changing is no longer permitted, or at least not without spending action points.
Just my 5 cents.
