War Stats?

[Gamemako]

How the bonus is applied is determined by the type of bonus that can be broken into 2 categories: *increases* to a percentile value (like critical hit or evasion chance) and static bonuses are additive whereas decreases to percentage values (what we normally call damage reduction is actually written as "reduces damage taken" so it is a decrease, not an increase) as well as any modifier to an attribute that isn't limited in any way (like the stuff listed on your character sheet) are multiplicative. Debuffs are in the same category as their relevant buffs.

While that is technically true, it sort of ignores the problem. There is no ambiguity with bonuses that are not percentage-based. Other effects which have no associated stat, like evasion or attack speed, and those necessarily have to be tested to know (and I don't think anyone ever determined whether Featherfoot is additive, multiplicative, whether or how it stacks with blind, etc). However, FFXIV has stats affecting percentile values which are themselves not percentile values, like critical hit rate. Inner Release description states: "Increases critical hit rate by 30%." What it actually does is increases the chance to critical hit by a flat 30%, and it does nothing involving the critical hit rate stat. This would have an exact analogue in the description of Berserk, which states "Increases attack power by 50%, except that ability does exactly what the description states -- "Increases [stat name] by X%". It just ends up being pretty sloppy.

Is it?
I had originally thought that the effect of Wrath and Inner Release were considered multiplicative off of your base crit rate, not a flat bonus. If that is the case then my mistake.
Sspd I am personally unsure of, it takes a ton of Sspd in order to receive an appreciative gain, same with Det.
Do you have a link for their values?

Specifically crit rate is a stat that suffers from what's known as diminshing returns.

Each extra point of crit is exponentially less valuable than the last.

Best illistration of this model would be for exageration sake lets say you have a 99% chance to crit it is safe to say you have almost no chance to not crit and as such any additional crit rate is pointless.

Bit extreme of an example but the close you get to 100% chance to crit theess chance you have to not crit which lowers the value of crit.

Sorry for the wall o words.

Closer to 100% chance to crit the less...* posting from my phone won't let me edit.
