Well, I'll just add my 2 gil to the conversation just for the hell of it...

Speedrunning Amdapor is much, much harder than doing it the normal way. Not only does a wipe on a boss mean you have to start over again through the gauntlet of doom, but the actual run requires more coordination and gear (at least for the tank) than simply killing everything. None of the trash in Amdapor is hard if you fight it as a single pack. The run is much more dangerous and is the closest thing to "excitement" you can get with boring trash mobs.
