Stat priority for a red mage

[Megguido]

DH>crit until DH+crit>3500 last I looked, then its crit>DH

People made a google sheet with the different stat tiers, and by how much it boosts damage: Nemekh's spreadsheet

Direct Hit is a linear stat. Every 100 DH gives about 0.65% damage.
Crit is a non-linear stat. 100 Crit gives more or less depending on how much crit you already have. And this tier we can reach high amounts of crit (more than 2000).

For example, at 1500 Crit and 1500 DH (which is totally doable as of now), every single point of Crit gives more damage than DH. Then, why focus on DH ?

I'm not a RDM expert, but I'd say focus on Crit > DH > DET > SpS.
