I just use Garuda so no one will bitch at me about, being noob or not know what they're doing. I'd like to use Ifrit-egi for the dps, but last time I did that some a-hole called me out about it and nagged me to use Garuda saying, "Why aren't you using Garuda, Garuda gives more dps blah blah blah."

Using Garuda = no one bitches
Using any other egi's = someone will bitch

So in conclusion: I use Garuda to shut up the a-hole crowd.
