How is SMN overall dps?

[ShinryuReishiki]

Since pets only benefit from MD, INT and Crit the value of DET using Ifrit is the lowest.

You should do another test. Determination definitely affects pet damage. These ranges are from just letting Ifrit attack on Obey for 10 minutes.

80 MD, 597 Int, 295 Det (http://ffxiv.ariyala.com/P331)
- Auto-Attack: 104-115 (156-173 Crit)
- Burning Strike: 199-220 (299-330 Crit)

80 MD, 597 Int, 424 Det (http://ffxiv.ariyala.com/P32Z)
- Auto-Attack: 117-130 (176-195 Crit)
- Burning Strike: 211-234 (317-349 Crit)

I can agree that Ifrit does more damage in some places then Garuda. However, his survivalbility is lower on average as well as you spend more MP on recasting expensive DoTs /Sustain, which also increases the MP drain over a long fight. Fights where the SMN can get exclusive Ballads would probably come out more in favor of Ifrit.

It really depends on the fight. For example, Ifrit has no survivability issues in T10-13; I've never needed Sustain unless I've made some sort of positioning error, like letting it in front of an add instead of behind. In fights where the boss has a knockback or circle AOE, it can be an issue, so I'd much prefer Garuda in such encounters.

I get 0 Ballad in T10-12 and I have no MP troubles. I do get it in T13 still, but that's more on the healers' needs than mine. You have to play slightly differently when using Ifrit, but the lower reliance on Ruin II actually makes the MP consumption very close despite the loss of Contagion.

I've been practicing getting comfortable with Ifrit and so far I can maintain 30 DPS higher than with Garuda over 10 minutes.
So I'm hoping in FCOB this week it will be an even greater increase since my group runs a Monk and War. (Hoping for a 45 dps increase)

That might be possible on a dummy, but in an actual encounter, the blunt/slashing debuffs won't make that big of an improvement. Especially on adds, there's a high chance that at least some of the attacks will happen before either debuff is up.
