FFXIV Elemental Resistance change

Can we have a change in the future over how elemental resistance works? Or rather, a buff to them in general. As it stands now, it takes a lot of Materia and ffxiv gil just to make a significant difference in the elemental damage you suffer and the effort does not match the reward. If anything it would add more depth to the game to give ffxiv players a choice to put resistance materia on their armor in order to decrease incoming damage.

Edit:

Allow me to be perfecting clear here. Crystal clear. 

I AM NOT TALKING ABOUT THE DAMAGE YOU DO BEING SCALED WITH ELEMENTAL RESISTANCES.

That would just ass a whole level of complications and exclusions from parties that we don't really need. Tanks are already being excluded from some parties apparently for not doing a certain amount of FFXIV DPS and that already is insanity to me. I'm talking about the damage you receive being lowered as you increase your elemental resistance through melds of CRAFTED GEAR, NOT DUNGEON/RAID GEAR. We already can't meld materia to dungeon gear--that isn't happening ever, and there's nothing showing that it would ever happen as they made a point before in saying "No. Meld to your crafted gear. Also eat more greens. They're good for you." I'm pretty sure Yoshida said that about eating greens... or if he didn't he should. They are good for you.

Dungeon/raid gear is unique in the fact that it comes with a preset build of stats for you already there and cannot be changed. If you were allowed to change what stats are on raid gear, it makes that gear far less unique and just stronger mirrors of crafted gear.

I'm pretty sure they wouldn't have to have dungeon dropped gear have materia slots as they don't do that now despite the fact that the far more "useful" critical hit and determination materia COULD be slapped onto dungeon armor if they allowed it but they don't and you can't. To be honest, I firmly believe that having identical gear with different materia melded onto them is the point as it adds variety to crafting and the battle system. I currently have a set of Wootz armor for each element. I don't have to imagine it as I did it. Was it expensive? Yes. Was it fun? In my opinion, yes as I had to make each armor myself and raise up the money in different ways to afford the materials, materia and carbonized matter (I got lazy, I'll admit it there with the matter) in order to make the armors.

If they would put in a system where you need to use dungeon gear for melds they would have done it already considering we could have made our own BiS gear from Coil 1 with savage aim and might materia. I'm talking about crafted gear. I'm even betting it would be better for the market boards as it would give people more incentive to buy or sell elemental materia for melding.
