Just wanted to point out, this only mostly works. I recall while leveling DRG, there's that weird middle-ground gear that's for tanks and also DRG. It's pretty low class tank gear (imo), plus the tanks already have tank-only gear. But if you're running DRG, you do not get the option to Need on that particular set, despite it being generally pretty good for the class/job (at least I thought so, it made a nice alternative for "I want to live" gear, rather than focusing everything into dps).

But anyway, re: Needing for GC seals, wouldn't it be so much faster/easier to FATE grind for those? I mean, I don't know how much you can get out of higher end FATEs, or what the conversion rate is for higher gear sets. And I know FATE grinding is a bit mind numbing (although be honest, dungeons aren't often very exciting either). But seems like you could spend 20-30 minutes rolling FATEs, and get as much or more seals as you would from Needing gear. But I could be wrong I guess.
Desynth is still valid, I suppose.
