is a internal resolution scaling option difficult to implement?

[DrFlesh]

lets be real, the antialiasing solution ffxiv uses is bad.... REALLY bad and we know that's because they used a deferred rendering engine, when warlords of draenor released and blizzard changed to a deferred engine solution they had the same problem, antialiasing was bad so because they got input from the users they implemented a internal resolution scaling (better know as downsampling) slider for the game and it only took 2 months to implement, would be hard to implement this on ffxiv? would the pc players try and push this so the developer team gets feedback on this? the difference on graphics from 1080p to a downsampled 1440p pretty big on games like this

sry for my bad english (not my first language)
