Well from what the OP was originally writing, I am assuming that he was trying to find a use for Ifrit in day to day events, not specific fights and builds. As you pointed out Ifrit does have use when conditions are right but only then. This is why I feel the base pet design needs to be revamped. Most fights that actually require a stun or silence, pet stuns are a hindrance rather than an asset. Titan lacks the enmity generation power to become an emergency tank when things go bad (I've tried this a few times but didn't work well). When the debate comes to which is a better DPS to use in every day activities, Garuda win.

I do think it would a good idea to update the original post to state which fights and situation that Ifrit is good for so new comers know.
