It is a nice system... but like so many things in FFXIV... It's a fantastic supplement to the established system, not something that should try to masquerade as the core of the system. If you get a party started (say you get your healer and tank) and don't care about the other slots, or someone has to go, and you need a replacement, yeah, this works really well. But when you're looking for specific things, and you wanna ask around, this just doesn't work. Plus sometimes you're looking for someone your friend told you had high smithing and you wanna see if they're on to make you a new weapon.
