I can fully understand why they didn't want to increase the Maximum number of Merit WS obtainable by any number. Its true, We're incorrigible when it comes to this "Universal armor/weapon" Crap. I was never a fan of the "If they give us this, people will whine for that" excuse, but seriously I understand it now.
There's like, 3-4 Jobs out of all of them that would benefit from a Universal AF4, and even of them there would only be about 1-2 exceptionally worth-while pieces per job of those three, and they'll be Mage jobs. It seems like a largely unrealistic goal for the current Dev team and beyond that seems largely ineffective
You're essentially asking them to dump numerous man-hours into saving you a few inventory space and macro slots. While inventory is stupid tight, You're looking at maybe realistically 3 cleared inventory spaces based on your job if you combined A/R/E armors. I think they're going to need a d*mn good argument for this outside of "I'm anal about useless stats so I need to carry around my THF AF Vest at all times for the hide Bonus, it should be on my AF4!!", cause most of the bonuses on AF/Relic are negligable to crap, with such few gems in them for so few jobs this whole concept seems dead from the get go.
Not to mention the 4 category limit on Armor, and If they added the rest to Augments the f**king armor itself would look like a book by the end of it all. Further, how would they make this armor or obtain it? You wouldn't be thinking some practical yet challenging right? I bet it was something like "Get all 4 Pieces and trade them to a magian moogle and its combined and done!".
Are you going to include Augmented Relic+2 Stats on these sets? Are you going to include special bonuses from AF+1 that AF didn't have? (i.E Trick Attack Bonus on AF+1 Hands for THF). If so, do you people really just don't see how Impossible and improbable this would all be? Do you not understand how broken a pair of AF4 gloves for THF would be? I mean, Assuming they're not Item Level 120+ You're looking at.

While it doesn't seem far and beyond to OP'd compared to recent armor, Theres far too many categories on there, And thats not even the most text worthy one, and its excluding Bonuses from the NQ versions of AF/Relic... I mean, if you delve into RDM or SCH or WHM or hell even MNK, You get into like 9-10 Lines of text for 1 piece of armor, Not only is it well above the 4 Category limit, if you add the rest on the Augments, How will you get the Augments? What will be decided as Augment or Base Stats? Will they combined 1 by one and they have to go in a specific order and have to code a+1/+2/+3/+3augmented Piece just to obtain all the stats on them?
So on and so forth, This isn't as easy as slapping +5 Stats and +2 Affinity for Magic and calling it a day... It would be much more complex, and horrifically time consuming if it was even possible to accomplish.
While I'm all for saving space, when you actually take the time to look at the unreasonable amount of effort involved in this request that would only benefit a handful of jobs, and how you'd implement it and so forth, it just seems like an impossibility unless you're willing to wait 3-7 Years for it... If Cait Sith, who already has Attack Animations, Bloodpacts, and so forth, has taken over a year and still has no signs of being implemented, this type of system will be on back log long after you guys die of old age.
Anyway, this is fun, so here's some more unrealistically high-in-text examples of why this system is absurd.

Edit: I should mention the idea isn't inherently bad, if not a little unrealistic and silly, Its just... well... nearly impossible, and even if you pick and chose which bonuses make it to the AF4 you still get an incredibly complex system that will at best save you a few inventory spaces.
