If you take inconvenience to mean obstacle, do you really need to look past sky when it first came around (or even just the zilart missions, and divine might)? old CoP with caps and figuring out how to deal with Sea NMs? even the aht urgan crap before it was stuck into wikis. granted as time went by they made it easier and easier until it declined into its lack-luster (easy mode) current form, more like WoW, more like XIV is currently. But hidden among the bullcrap waiting for things like airships and parties (seriously, you could party with your LS's anyway like people say to do now in XIV) there were a huge number of obstacles.
