For most of us 1.0 players, we know what Hamlet Defense was. For others you can find the information here: http://finalfantasy.wikia.com/wiki/Hamlet_Defense

Hamlet Defense brought about a nice focus for all classes DoH/DoL and DoW/DoM. The Preparation Phase, mostly for DoH/DoL, gave most crafters a feeling of fulfillment and usefulness. The Supply Caravans were also pretty fun. It was like it should be, prepping for an all out battle.

Then came the warfare phase, where players both DoH/DoL and DoW/DoM, had roles to fulfill in a instanced battle to protect whatever. One of the rewards were beastribe seals used in our relic reborn quests.
