I cant understand it. Garuda is caster, Ifrit is melee. But garuda is applied melee accuracy now.
So SMN need more accuracy ~20 than BLM. This is connected with a bit dps loss.
And now in 2.4 most of ironworks and dreadwyrm have too many Spellspeed. Known stat weights as follows:

BLM WD: 6.625; INT: 1; CRT: 0.215; DET: 0.283; SS: 0.24

SMN WD: 6.57; INT: 1; CRT: 0.211; DET: 0.283; SS: 0.094

BLM is OK. But SS is really useless for SMN. I replaced SS with Piety, use 110HQ melding to solve SMN's MP issue.
24 piety give me that dummy battle timers increasing 5min -> 6min.
Why Garuda is only applied SMN's Acc?
I think that SS apply to SMN's Pet. Then SMN's SS is more efficiency than now.
