I like you, you like to point out my own words to argue, which is proper. Some points are missed though, which isn't something I'm immune to obviously.
Regarding the THF AF, I brought that up because SAM was released at or around the same time as AF2 (Dynamis). Again, we're talking about a period where the game has undergone changes. I mean, my mention of THF having +shield and +parry stats on it's AF1 is evidence of one of many instances that proper stats aren't exact that games strengths, cuz as you know, those are tank stats.
Hell, THF had +INT on it's original AF lol. INT for THF was only useful for its elemental WS abilities, and even then, it really wasn't a good stat to bother with since the WS didn't stack with SA/TA and SC'd really poorly. This is due to better WS abilities emerging like Dancing Edge or ones with better SC properties... even Viper Bite was better to use in those early level cases. Sorry for the tangent on detail lol.
But I agree with needing to agree to disagree on it.
Good catch on my poor word choice. You're right that it doesn't work against you, but it doesn't exactly prove one over the other, which I'm assuming seems to be the point. To be able to justify why one works over another.
I wouldn't really say "no one" on their thinking SAM must be tank, as there were some in this thread earlier ("righteousness of sword users = tank" bull**** that was brought up at some point), but I agree that most aren't of the "impossible" mind. Likewise with the folks that want it to be DPS, not tank.
I'd assume most of them are accepting that it's possible, but they think DPS is much better logically. To that, they're wrong too sorta lol. Practically every point on the matter is interchangeable, as you and I have noted. The only grounds that pro-DPS arguments have is XI, for two reasons. 1) It's a DPS, through and through. 2) Even if it was intended to be a tank there, that means they couldn't pull it off successfully (not a remark saying it can't be done, mind you). Are those points meaningful? Who knows, that sort of stuff is up to the devs.
You're right, they aren't as common as here. But you know what was different about it? They weren't telegraphed, and most abilities that mobs used were instant or near-instant... and VERY common to 1-shot non-tanks. You weren't going to avoid that Radiant Breath, Bad Breath, Heat Breath, Dark Spore, Silence Gas, Blank Gaze, etc. Just to clarify, there actually were a ton of frontal cone AoE in that game and many of them were very dangerous.
If you stood in the front of the mob all the time as a SAM for no group-beneficial reason, you were HATED in that group. Tanks found you annoying, healers REALLY hated you because you'd be 1-shot or they need to remove various debuffs that not only likely damaged you greatly, but hindered you to the point of being useless. So yeah, if you did that as a SAM, you were a bad player.
Edit: SAM is not the only job with risk factors as well. THF, for example, is the only job that technically would stay in front for longer than the SAM for the short time they would. TA+WS was a very common means to keep threat on the tank from powerful DPS doing their thing. This means THF does, in fact, go in front of the mob to do their thing. So... yeah, SAM is not the only one with mechanics or factors that involve going to the front.
... actually BRD would too sometimes. Depending what the tank specifically needed, compared to what the other jobs wanted. Forgot about BRD on that, and I used to main it too lol. Seriously, you should drop the trait argument. Come at me with something else... you're not gonna prove your point on this one, because it just doesn't apply to how the reality is. Now if the trait did something to mitigate damage full-time, I'd be right there with you on it, but that's not the case.
