I've been more on the side of "learn to deal with your limitations" than most over the years... But surely you can't agree that it makes sense that if you're soloing and you get Blinded or Silenced while at dangerously low HP, the automaton will fix that status effect instead of give you the cure you need to survive.
I agree that if your priority is curing a tank in a party, you should stand back - and fixing -na/cure priorities doesn't change that. You would still get spells targeted toward the master and automaton ahead of other party members, so you need to take extra care to not lost HP or get enfeebled on both master and puppet. Stand back with a light and water maneuver up to force the puppet to toss cures on the tank.
