Summoners and Spell Speed

[Nemekh]

The substat priority for SMN is Crit > DH >= Det > Sps, with the goal of minimising sps as much as you can without compromising your ability to perform 11 wyrmwave Summon Bahamuts - with or without Addle being used. That is what's recommended by our guides over at The Balance (including Kodas and Imouto's).

We minimise sps because we gain the least from it by a significant margin due to Bahamut's raw damage, most pet actions and our oGCDs not benefiting at all from it but also because our Ruin GCDs are fairly weak. Sps does scale DoT damage but by itself is not enough to swing it to a stat we want to seek.

Clipping is also a legitimate concern but it all depends on your latency. You will never have so much sps that you clip on single weaves, however, double weaves are where clipping will vary with latency. That said, apart from the opener the job is not as intensive with double weaves, as such, you can worry much less about clipping your gcd.

If you want to set yourself a gcd limit, go no further than 1316 sps (2.35s gcd) as this is the general range your gcd is rolling too fast for Festers. A comfortable range is between 2.48s to 2.39s however your preference may vary. While you don't raid, you can build towards these BiS lists and focus on the tome pieces and melds they have:

i400 2.45 gcd

Hopefully there will be some solid pieces from the final 24 man when it is released!
