tl;dr

Bring back force pops, as well as open world spawns - but keep the time windows realistic this time. Please, no more Zilart Kings nonsense of mobs that pop once every 24 hours, and then a small chance of an HQ pop once every week. People have lives, and this is a game - the challenge should always lay in defeating the NM, not throwing your life away to camp hours on end.

Oh yes, and REASONABLE DROP RATES! Please. no more items with less than a 5% (if not 10) chance to drop. Rarity is important, but not at the expense of everyone's sanity. Maybe bring back some of Abyssea's weakness-targeting mechanics. It doesn't need to be exactly like Abyssea, but I do feel that performing complex/stylish combos such as Limit Breaks should influence things - basically, reward strategy.

Spoils should go to the first group to claim, unless everyone is K.O'd - we don't need the old drama of XI where entire alliances would stand by for the first chance to steal it away as soon as a tank went down.

Not sure about loot though - is it better to have a small % roll for everyone's individual pools, or simply drop items into the leader's pool and let them decide how to hand it out?
