In your first macro, you're setting Kelanar as the focus.

In your attack macro, you're assisting your focus, but then casting your spells against your focus-- Which is Kelanar.

It's unnecessary to keep re-focusing Kelanar. Additionally, you should select whether you're going to assist him/her, or focus and attack your focus' target

Change your cast macros from "[target=focus" to "[target=focustarget"
