1) Make all the armor dyeable, people will do crazy things to get the glamour they want

2) more minions! Cerberus I know would be popular, possibly Scylla. Maybe a magic put for that boss fight? Doesn't have to be the boss itself, can be something else related to the dungeon. Again, people will farm for minion drops.

3)every boss chest add a single random drop from Alexander Normal. that's one for each party for each boss. Make it chosen from the entire range of upgrade items so that you have reason to try for the final boss instead of dropping out if you don't get your desired item.

4) Give Law tomes for the final boss fight. For the weekly quest reward, add Eso, give *all* the ironwork upgrade items and a choice of an alexander upgrade item. Possibly even a savage upgrade item, as it would still take many weeks to upgrade a single piece via that. (IIRC, I haven't gotten around to poking savage yet, but I recall the upgrade requiring multiple tomes per item)
