A slightly different setup that works good

[Powerwar]

I am not sure I understand...you CLICK in your non-main WoWs to refresh totems?

No, unless the main is dead. But I can click on the main and cast different spell while the n on mains are DPSing. For example... the non mains are casting a bolt while the main is healing, refreshing a non stacking totem or whatever else.
It basically allows me to have the main do something else than the companions and that is not scripted, so it can be completely random. And I have to click ONLY if I want the main to do something else.
In world PvP where you get jumped out of the blue by several players this turned to be quite good option.

I have found a great improvement against groups with skilled hunters. Basically the hunter sets his pet to kill my windwall totem all the time, so while the companions are killing the nearby rogue I have the main refresh the windwall totem. You may argue it's just 1.5 seconds difference, but when you are vastly outgeared every second counts.

The usual setups I see in this forum are mainly using one only bar, while I use all the bars.
