I have finished "The Ultimate Weapon" quest, and I have to say it was pretty fun. I especially liked how the Magitek armor even had working weaponry during it's sequence.

Now that we have one for a mount, I was wondering if there will be more opportunities to use the armor in combat, say special quests or storyline quests in later expansions. Despite the outcome of the main story to this point, I can imagine that Eorzea won a battle, but the war with the Empire will continue for quite some time, even if it's a cold one. I can also imagine that the Empire would continue to improve it's war machine, being the ruthless conquerors they are, and that there would be some that an adventurer on foot can't handle.
