1. Linkshell Message -
Will be in 2.0
2. For the game to Activate my crossfire

-
the new engine will support this... i hope
3. Gear Swaps (I know some people hate this but i hate staying stuck in one spot for 3min because i switched a ring)
Will never happen, SE said no and that it will never change their mind. One of the reasons for this Is that your weapon controls your job and SE also plans to prevent you from changing jobs in some future dungeons/raids. Will never ever happen pple get over it and stop asking.
4. HNM's (epic dragons etc) Odin in 2.0 sounds like HNM.
Don't think we will ever have HNM but we will have something smiliar
5. Sky/Sea Type content (no more Instance)
Yoshi-P said he wanted this for a future expansion, after 2.0
6. Be able to trade more then 4 items -
Maybe 2.0... new UI
7. Real Airships (Not a CS) -
Will never happen thank god for the skippable CS. Pple who ask for 10 min airship rides dont play much. Now if they put airships that travel you between crystals and not just cities as an alternative then yes i am all for seeing you travel there for the whole time.
8. More weapon Variety (not to be locked to a job or class by your weapon) -
Won't happen the whole class/job system depends on weapons. They would have to re-do the scratch system from scratch which means re-doing battle and a whole bunch of systems from scratch which wont happen.
9. Crafters Signature plates for armor (So crafters can be admired like on XI) -
Coming in 2.0
10. Skillchains (Make People have more fun with weapon skills) -
Not sure what you mean by that. Aren't combos already skill chains? You mean more combos?
