DRG = low ACC
NIN = high EVA
Drg has to spend more gil to get the same acc+ but they can do it(scorpion harness, specs, etc). And they have acc up trait at 30 to put them ahead or cancel out any differences. If anything drk's the inaccurate one by nature of the job.
Ninja's evasion is quite good but it's worthless compared to a thief's.
The only reason I'd favor a ninja in a 1 on 1 matchup is because a polearm would have a hell off a time getting all a ninja's shadows down. Although wyvern+drg together might take shadows down reasonablely well actually though. Polearm+wyvern+polearm+wyvren+jumps= openings for attack. I'd probably have to give this match to a ninja though.
Drg could do a good number on most jobs though, especially with subs allowed, drg/whm.
Thief with dagger(s) would probably be one of the better counters to a ninja 1 on 1. We'd by far have the most chances to bring down shadows as fast as possible, and keep them down. I wouldn't be afraid of their attacks since my evasion would be far better. But I'd fear a ninja for their elemental tools, I consider them far more dangerous than shadows I can chop through, and we have the exact same hp too, it'd be cool to see.
I'd love to see some classic matchups though such as:
Drk vs Pld, pure opposites in figure and approach
Drk vs Drg, two highly compared jobs
Thf vs rdm, so I could shut them up, they'll be too busy despretely trying to keep their buffs on from my fast attacks and triple attacks to have time time to do anything offensive. And once their buffs come down, they're not going back up or will the get to finish any casting against me.
Ranger vs Monk, the best damage over time endgame from each, no casting to worry about. I think it'd be dead even in terms of their damage output but my gil is going on the monk since the huge huge huge hp pool gives off an incredible advantage.
Whitemage vs blackmage, who's going to last? Will the blm put away the whitemage early or could the WHM last long enough through buffs and cures to get to a empty mp situation on both sides, where whm would have a clear advantage? Besides this is pure good and evil
No one has even mentioned bst, I'd be frightened to take one on more than anything, it'd take any of us forever to solo a jug pet at high levels. 1hand axe is low delay too. Between a bst and its jug pet(s) it'd take FOREVER to kill if you did, they'll have more basic attack power between them, and between a bst and his pet, they could tear through buffs as well if not better than a thief with his dagger and triple attacks.
