As a synergist, I am happy about this update and can't wait for it to be on game. My craft was always useless and not required, but now I'll finally be able to help my friends upgrade their armor!
And no I don't think SE had a bad idea, they are not trying to make AF3+2 obsolete. More like, they are trying to make happy all those people who have been doing endgame for the past years and that have been thrown off at how all their so hard work to attain that gear had been destroyed by new, relatively easy to get armor. I haven't been on endgame much, but I was bummed to retire some armor like byakko's haidate or askar zucchetto for... full perle. It made me look like 60% of the DDs around and I felt less individual. So yay for this update and I hope salvage/assault armor is soon added too! I'd love to see people into Assault again!^^
