Speaking only about Abyssea and the utilization of Atma of the Razed Ruins/Atma of the Voracious Violet, Jupiter's Staff might just be better DPS on exp mobs. My current tp gear is decent (AF3 pants +2) and I have 4/4 Critical Hit Rate merits. The Razed Ruins atma gives +30% Crit. Hit Rate, so I total 52% critical hit rate on RNG in Abyssea.
I noticed very little difference in Sidewinder/Refulgent damage but critical hits from Siege Bow with Demon Arrows are between 350 and 400 damage per critical shot. With Antlion Arrows, the damage increases to 400-450 damage per critical shot. With the addition of Stalwart's Tonic, Antlion Arrow/Siege crits increase to 500-550 damage.
Factoring in Double Shot, that means back to back critical shots cause 700-1100 damage...
With all the new "Increases Critical Hit Damage," I can see ranger DoT relying on critical hits in the present or very near future.
So, I suggest that if you have the Razed Ruins atma, you should try out Jupiter's Staff instead of Vulcan's Staff.
If anyone cares enough to perform a legitimate parse comparison, I'd greatly appreciate it and would love to know whether I should be getting some more crit gear.
