Glad it worked for you. I have been looking for a quicker way to assign focus as well. I wish gladius had a keybinding for "focusenemy1,2,3" etc... but nothing. 97% of matches (not ROV) start with 10 secs minimum of pillar humping... so I click a target, hit my LB or CL (1 or 2) causing them to assist, then i assigned a free keybinding to a "/focus target" macro, simple but it works. As soon as i hit assign focus my shamans target themselves again, so youre not running around with 3 shamans pointing at your "secret" focus.

I'll think of a better way but for now it works fine.

And also, in ROV, or when you get rushed in any arena, its not worth assigning a focus anyway.. usually. But just click someone and BOOM it works just fine without a focus as well.
