Ironworks vs WoD

[Kietsu]

Did you actually do the calculations? I'm using the most recent stat weights I know of as of 2.4:

Augmented Ironworks chest: 47 crit x .215 = 10.105 INT + 33 spellspeed x 0.098 = 3.234 INT + 5 extra INT from being i130 vs i120 = 18.339 INT.

Demon Robe: 31 crit x .215 = 6.665 INT + 31 det x .284 = 8.804 INT equals a total of 15.469 INT...REALLLLY close to the Augmented Chest, but not "better" by any means, and that's not including the extra VIT you get from upgrading.

However, as i120 vs i120, there's no contest - get the Demon Robe.

This math is really solid - for Black Mage. But OP is asking about Summoner gear here, where Spell Speed is very much ignore-able - DoT ticks aren't affected by SSpd, Egi attacks aren't affected by SSpd, Fester, Rouse, Rouse More aren't on GCD - the only constant damage output effected by SSpd is Ruin, which has a potency of 80.

Mind you, I'm not a Summoner, and the only reason I dabble in it is because I mainly play Scholar, but I do get the feeling SSpd has no value to them.

Pretty sure that's smn stat weights. Spell speed is actually the strongest secondary stat for blm, valued at just under 0.3 int each, while for smn its under 0.1 int.
