Scale back Critical Hit

[Amenara]

And that's where we need to look at the functionality of stats. Direct Hit is the second best stat in the game next to Determination, as DH provides a chance of dealing 25% more damage and Determination raises your damage floor and healing done. Critical Hit infinitely scales upward in terms of the rate it can proc and the damage it can deal.

If we're to look at stats as a whole, there are a few stats to consider reworking:

Tenacity - Tank-only stat that reduces damage taken. It reduces damage taken very, VERY slightly, and only slightly raises damage done. Not a good stat to invest into.
Piety - A stat that Healers are familiar with, they typically only want to reach a certain piety(even if that Piety is 0 on gear and melds) to be able to handle their MP Economy effectively.
Skill/Spell Speed - A stat that determines your GCD. Definitely needs looking at, as its only purpose is to enforce certain GCD tiers and not provide much else. It's been the bane of some jobs' existence as well.

I think I remember reading somewhere about Yoshida wanting to redesign secondaries at some point but I am not sure where he talked about it. I agree, Tenacity is a junk stat because of how poorly it scales and how little the damage reduction matters with the biggest concern being tank busters instead of steady damage throughout a fight along with healers being very strong in the healing department. I wish there was a way to make skill speed akin to haste stat in FFXI, but unfortunately that would require a major combat rework to make auto-attacks more impactful and have a lot more of your skills CDs affected by the stat (bringing us closer to WoW combat I guess :/ ). Piety is more or less a junk stat I imagine got implemented because the people who redesigned substats in ShB ran out of ideas and if I had to guess and expected MP economy to matter at some level.
