Vulcan's vs. Jupiter's staff (bow)

[Alderin]

Ok this question is for the Gandiva users. I know Vulcan's is better for gun due to fire affinity however my question is this -

Why do so many (if not everyone) I see with Gandiva use Vulcan's over Jupiter's staff?

We are basically looking at +10 R.Attk vs. 15% Crit Hit Rate.

On paper (as I am yet to parse this) Jupiter's with fairly standard gear will increase DPS by about 10%. If we are talking purely overall bonus, vulcan's staff offers (from my terribly rough math) a ~1.3% boost in R.Attk for a lvl 90 RNG (Due to a lvl 90 Hume RNG having about ~820 R.Attk). Yet Jupiter's offers a solid 15% boost in crit hit rate.

So in *theory* Jupiter's is a stupidly overpowering main hand boost compared to Vulcan's..

What am I missing that Vulcan staff users know about?

That Jupiter's Crit rate affects only the staff.

Nevermind! case closed. Cheers for enlightening me.

Oneiros knife and augmented Yataghans are also an option, assuming not /sam and/or using Hasso/TE.

That Jupiter's Crit rate affects only the staff.

Wow - I am fairly new to RNG myself, and was unaware this distinction existed. Is it specific to certain gear, or does Critical Hit Rate never apply to ranged attacks?

I was looking for support for this, but all I could find was a discussion entry on FFXIclopedia stating that it was unlikely that it affected ranged attacks (citing examples of a couple other items).

If this is the case, is it all +CritRate sources, not just gear? When we set RR are we only getting the +CritDamage from it?

Thanks in advance for any answers, clarification or evidence.

crit rate on weapons only effects that weapon. crit rate on gear is universal, crit dmg on weapons/gear is universal.

Now, if only more Rngs knew and understood this. Would make for a lot less crappy RNGs out there.

Thank you for the answer - and again, I am not disputing this - but is there research I can read about this? I should have been more clear that data is really what I was asking for, as I still cannot find anything explaining the researched distinction - entries in both FFXIclopedia and the BGwiki don't explain it, and I have had little luck locating threads on the subject; though I might be looking in all the wrong places.

Mostly I want to be able to direct people to the data; in small part, I just enjoy reading all that nerdy stuff.

So, to anyone out there, can you provide a link or some direction to research about this?

Trollsclaimer: Restating that it is the case is not necessary - as I have already conceded that I was unaware of the distinction, can comprehend what has been stated, and I am not arguing its existence or truth value.

rng forums on ffxiah are a source. also random question thread on BG (after using search function). there may also be a critical hit rate test thread on bg or AH somewhere. my source of the info comes from knowing how the senj-katana works (ie. not in off hand for ws)

Crit damage: Fire some shots at lvl 1 mobs and record criticals. Equip crit damage yatagans, shoot more and record numbers. ranged damage is very consistant, it'll be easy to spot.
Crit rate: Open parser, fight in an exp party for a while without Thunder Staff, note crit rate. Reset parse, repeat with thunder staff equipped. If it worked it would be very noticible on the parse.
