So I've been giving this some thought, and really the more I think about it, the more I realize the bonus stat system in the game is worthless. The biggest reason for this is because of how the stats themselves work, they are very streamlined in what stats do.

I'll use FFXI as a comparison. In FFXI the 2 big DPS stats for physical characters was STR and DEX. STR affected damage regardless if you punched things, bashed things, or shot things. DEX affected your ability to do crits and your accuracy. By comparison in XIV STR is damage for melee, DEX is damage for ranged and that's all they do. For a job in XIV you only want the corresponding main stat for the type of damage you deal (STR, DEX, INT), the other stats do nothing for you. So in XI as a DPS you balanced out DEX and STR, your ability to hit things vs your ability to do damage to it. In XIV you just load up on one stat and call it a day. So for example on my DRG I have 30 points into STR, because DEX, INT, MND, PIE do nothing at all for me. They are essentially worthless stats I just have.

Of course some people will argue you can at least put points into VIT, but even that I think most people find a waste of stats points. Firstly so many fights have hard DPS checks so every bit of DPS increasing attributes are beyond helpful to make so you can pass the check and push phases a little quicker. So any point in VIT is a loss of DPS. Secondly you get a good deal of VIT through gear, more than enough to do content. Most fights DPS shouldn't be getting hit to begin with other than a stray mistake here and there, or from big unavoidable attacks that your supposed to survive (i.e primals big signature moves). Often times if they DO get hit, no amount of VIT will help anyways, such as eating landslide, double wicked wheel, stacked plumes, etc. Too often the fights have just big hit attacks or knockbacks that make VIT irrelevant, it's a do or die sort of mechanic.

For tanks it's the same deal, you put all your points into VIT and call it a day. Tanks are about surviving, so they need to put points into stats that help them survive. A small increase in damage doesn't help them with this, especially when mobs hit extremely hard regardless of your ilvl. The only benefits tank wise STR and DEX give are an increase to block and parry, but because they operate on a long range to round up to a whole number instead of giving you decimal values, you would nee to pour in a lot of points into STR or DEX to see only a 1% increase of block/parry rate or mitigation. Something so tiny it can't over shadow an extra 700 or so more health.

Playing my tank in XIV the best way to tank is just to have a lot of health, there's not much else you can do to help mitigation as most of it comes from the parry stat, or cooldowns. Stat point wise all you can do to help with mitigation is have a larger health pool.

TL;DR version, stats are stupid simple in this game compared to other games and result in the bonus stats being 100% worthless as there's only 1 stat you should ever dump points into for your job.

So my question now, given how simplistic this system is why is the bonus stat points even allowed in the game? It only allows for people to risk wasting them in stats that serve little to absolutely no purpose, or even more importantly for classes like ACN that have 2 jobs, it forces the player to pick only 1 build (play SCH better or play SMN better), or to split their points in half and only play each at less than their full potential. This is a concern for those that like to play both SMN and SCH, and for all future classes that will get 2 jobs.
