no1 wants to listen to someone that whats to shutdown every idea they hear. Maybe u don't like these idea mainly because u didnt come up with them you're self or there not you'res i agree with wolf i have seen u on these forums some great ideas out there and u like that's stupid. Everyones idea is worth a chance so get over you're self and let people post there idea's and maybe see if you can think of an idea in that head of youres and stop being a troll
Anyway meld to the gear is an gd idea but there would need to be some real big price to pay to do it.
If you remember back in FFXI there was a ring you got from CoP and if you tossed it away you couldnt get a new one for 30 day's
Let's say new dungeons come out with some AF materia ok great, you can meld up to lets go 3 times to each piece but starting chance 50% since its a rare gear and meant to be only one of ifs kind. if you do pass the first meld go you

if you fail you got to wait from 10~30 days before you can get that piece back. That would be a gd punishment to trying to overpower yourself.
I can't see the dev's bring this to game they may pass our idea's on and will prob put a lot of though into it, but don't forget something like this need's a lot of though put into it so no1 crys over something being done wrong. Like really if you wont to get powerful in a game you got to pay the price or work your little ass of to get that goal. We just can't have 3000 people running about on PLD with + 2500 DEF.
Also read some1 in here said something about upgrade like back in FFXI also great idea,
Great idea man tho but need's a lot of planning.

EDIT!
Just saw another post about melded gear should be number 1 gear i don't think so, Most people in this game dont brother making money so there only going to maybe in you're LS 3 people or so with pure pimped out melded gear gear. Rare Drops should be the best gear in the game but hard to get meld should be come close to it. Plus most people anyway will maybe mix Droped gear with melded gear just to suit there needs with what ever set-up or job there playing.
