I don't care whether people clear and/or farm stuff sync or unsync. Those things are not for you and me to decide on.

There are benefits to clearing things when relevant (when at level AKA synced.) When I do clear the duty (e.g., Sophia EX, Zurvan EX, etc.), I have more chances of winning battles and obtaining totems for whistles down the road. Heck, I can get my mount before the bads and/or forgetful ones start ruining the farm parties.

Most unsync farm parties for EX primals after Bismarck and Ravana are rather horrible and wastes time wiping to mechanics instead of using skill and their unsynced powers to farm mounts as the party description says.
