- There's an npc (Shalo) to the left of the elias misc shop who does the item lock stuff. Note, you can't enchant or upgrade anything that's been locked and it takes three days to remove the lock.
- In terms of coliseum, maestro (bard subjob) is the highest dps class bar none. In terms of bosses/TAID/etc, ruin walker (treasure hunter third job) and highlander (warlord subjob) win. Basically any subjob is high dps though.
- Templar third (holy order) is the supertank, and now come complete with moves to force all enemies to focus on them instead of the rest of the party.
- GS/duelist is fairly obsolete in pvp and pve. But they do have a really good subjob.
