Or how about we expand the use of materia. Lets have it so we can meld it on blue battle tome gear because right now crafters can meld their blue tools this will make the so called crafting is irelavent relavent again by crafting gear to sell for spirit bonding.
crafted gear in 2.xx was meant to be catch up gear not build full set Over Meld then Clear New Raids in a Week. They didn't like it being used this way so they got rid of this so called option and yes it is a choice to buy it but some people would probly be blocked out of groups unless they had this and we know how SE hates this.
And as iv just said they should let us meld blue battle gear this can also give people the custom build choice that they want (not that there's really a choice but still) and it doesn't even have to be much just 1 or 2 slots won't make that much of a difference but would still give a bit of a boost. just low enough so it dosnt become mandatory.
