I'm shitty at formatting so I'll just make a list. The list isn't in a specific order of importance.
1. Two toned dyeing. Basically changing the 2 main colors of an item, i.e. changing the black part on Company Tabard.
2. Free Company PvP Tournament. The FC signs up in the beginning of the week and then the tournament would happen over the next few days. Winners get rewards and stuff.
3. Level 60 monsters that drop more valuable materials and are harder to kill. SE my be doing something like this with the airship exploration.
4. Consequences for a FATE failing. If a fate fails the landscape is changed i.e. FATE monsters running around even after the FATE is over temporarily. A new FATE will spawn that will change the landscape back to normal.
5. A Free Market. Every thing is sellable except for token based,relic, and AF gear. These include all green,pink, and blue dungeon items.
6. New Roulette for Expert primals and Crystal Tower.
7. PvP zone. Like a free battle zone
8.Gear sets that effect skills. I.e. a set that turns Blizzard 4 into an aoe. Or a set that increases Bios duration.
9. Stronger crafted gear, less emphasis on glamour more on effectiveness.
10. Turning off battle music.
11. I don't know if this one would be popular, maybe an idea for 4.0. Splitting jobs in half to specialize in a specific field. Like splitting Black Mage into AoE or single target. This would start at the split, not change how the job worked before. Could give them a cool name to, like Galaxy Mage or something.
12. Alternating animations for spells. Mix it up a bit rather than the same robotic character animations.
13. Magic scrolls that contain one spell. Can be a new crafter.
14. New super skills. Can be for 4.0. Basically has along cast time or(both) recast time Each job would have one.
15. Randomized Treasure Chests. One spawns in every area say every 4 hours in a random spot.
16. More character customization options. A shorter less pissed off male Au Ra, a big Miqote, a skinny Roe, a bigger female Au ra.
17. End ps3.
