How to choose materia for each class?

[SeriousxSarcasm]

Actually, for SMN, the tested secondary stat weights are CRIT (0.287) > SpS (0.195) > DET (0.192).

If you use Ariyala's to compare different gear pieces and sets you can compare their stat weights (BiS solver --> Show stat weights).

Ok, I've gotta ask since no one seems to know, What is "stat weights"? Is that how much you get scaled from the numbers? Or is it just people saying "these ones are better"? 'Cause All the guides I look at say SpellSpeed is your biggest ally since the new game updates.My thinking is even with a lower scale the fact that you get more DoT ticks (which is where a vast majority of my DPS comes from) would make a huge difference. And it still doesn't discount Det needing equal attention since it raises your overall Damage, and Crit damage would then scale off of that damage as well (last I checked it was 1.5x more than a normal hit, but admittedly, it's not considered completely accurate). That's just where my reasoning took me, I'm not one to follow BiS religiously tbh lol since half the time you see people explaining why it's often not the best build.

Edit: What I mean by that is that from a purely number standpoint, BiS looks great, but when tested actually in game, there isn't much difference damage-wise over the course of a long fight if you go Det or Crit. Det gives you more stable and consistent damage, whereas Crit gives you big damage, but relies a lot on RNG to do it. Although it's not likely to happen, you could potentially go a whole fight with only one or two crits, and you've gimped your base damage by not putting anything into Det. In the end, most people agree that they work out to roughly the same amount of DPS when actually applied in game, and a balance of the 2 is what you want if your focus is on dealing consistent damage instead of trying for "server-top numbers."

(also just curious, but does anyone know if DoTs can even crit?)
