Any SMN that always uses Garuda, is just shorting themselves. You have to use both accordingly when necessary. There are actually very few things that are that dangerous to Ifrit, that he won't survive simply from AoE heals and most of those tend to be in Savage coils only. As for the stun point, you could just leave him on obey and manually use the skills. Also the only things that needed to be stunned are like dungeon bosses, you know the ones you can heal through pretty much any mechanic?
