Better alternative to healing than /focus or /target?

I was wondering if anyone knows of a better way for healing than using macros that have /target /assist, or /focus. I know that there is a latency between the targets, so you have to wait about 1 second before you can assist someone who has changed targets and get the updated target. But the thing is, I've died a few times because I've gone to heal when I was low on health because of this latency issue.

But is there a better way of healing than this? I know that you can always make a macro for every heal that has every party member in it, but I do not have that many keys. Anyone have any ideas to make the healing easier than waiting 1 second after switching targets and then using the assist macro?

One I thought of might be if I could click a macro on my paladin, and have it so when I mouse over a portrait my priests will heal that portrait. But I'm not sure if that would be possible or not.

You can /target Azin /cast Heal

Not sure if that will minimize latency THAT much but it is is *slightly* faster to target a player by name than /assist or targeting focus.

Of course it kind of requires you to either reset your macros when you swap out of your X box (there are mods that make this easier) or use mouse clicking when you are out of your group.

target=mouseover

You can't click it though, you need to use a hotkey for it to work. You need to use it with the healer, can't do target=party1mouseover for example.

I used 3 macros for every charachter and pet once. A renew, heal, and power word: shield for everyone. I was using bartender to put action bars in the middle of my screen for easy clicking.

Both of these need to have the healer as the main, and unfortunately it sounds like you don't.

Depending on how many keys you have, you could put one key for each character, and use one/two more for modifiers to get different heals on each. With 7 keys you can get renew, heal, and shield to any party member, self included.
