My very first answer would be : avoid macro in healing or raising...
But since you're on PS4 could work...

The divine seal one is good but like the other said wait should be at least 1sec
To avoid overlapping skill

The macro i would suggest for you is virus/eyes for an eyes macro with target effect
/Ac "Virus" <f>

Which allow you to put virus on your focus target no matter who/what you're aiming at

...

And last but not least
DO NOT SWIFTCAST STONESKIN II
In any situation it's a plain NO
Your swiftcast have more value than 5 sec of casting

If people can't wait 5 sec, then let them die... you can't wait 2 sec of healing
