No, was just hoping you forgot the simple step of putting it in every characters key slot.

I guess the macro

/focus [target=Muhata,help,nodead]; [target=Mahatu,help,nodead]; [target=Mahate,help,nodead]; [target=Muhaty,help,nodead]; [target=Muhato,help,nodead]

Looks ok to me. Can you explain what it is doing/not doing? Do your characters have a new focus after using it? Are they just not following your new focus? They have a new focus but won't attack?

I personally use Leaderless/Targetless - Focus Based Hydra for my group, so I am just trying to piece it together.

EDIT: typos in Macros is bad inch:
