PLEASE stop telling summoners to use Ifrit!!!

try removing all your gear except the weapon, garuda's damage will be extremely low, at around 100 each wind blade, but if you remove all your gear on ifrit the attacks only lose a couple of damage (probably because determination scales with ifrit but not int)

Just did as you suggested. Ifrits auto attack goes from 60-70 to 40 his and burning strike down to 80-90 from 130 ish. I only tested it briefly, I am not a number cruncher.

Meanwhile Garuda goes from 180-194 down to like 120-130ish.

I would have to conclude that Ifrit DOES scale from int in the same amount as Garuda, the difference being that the scaling is split between his auto attack and burning strike, where as Garduda scaled directly into Windblade.

Again this is just a proof of concept not a conclusive study of dps.
If Ifrit is really as you say gimped and only spamming burning strike every 4 seconds, this could lower his potential, however it may be intended since his auto attack almost always goes off a second before that and he could suffer from animation lock preventing him from executing it at the 3 second mark.

EDIT: After actually watching Ifrit attack I am convinced that the reason he delays burning strike is because of his auto attack, animation lock must be it. But think about it, he is delaying burning strike by one second or so to auto attack which when added together are either the same or more than windblade , is that really a net loss of dps?
