even if the idea is nice, it will not pass, they will not create a whole new set of animation because you switch of fist. mostly because they will need to do it for every jobs that have different stance (and strangely you have a few). plus like the idea to have different weapon used by the same jobs they will prefer create a new jobs that will use this weapon and animation that put it on another jobs. because is not different than, creating another speciality. what they have said will never happend.
that said about the skill that will be revamped (if not take out) you have a few of them. and i think they will more work around the meditation skill and more flexible combo system, because soo far we are quite limited in the possibility.
i still wait for a no positional combo for the monk (yeah, because i find it silly to play a monk that play like a rogue), the chi blast! and maybe some skill that will allows us to charge the meditation. outside this the monk is kinda nice as he is right now.
about the trailer, my position is well know, the red lady is not a monk, what she is.... it's open to speculation, for me (as like it's my personal opinion), it's scream dancer... funfact, i did say a few years ago that i will find very interesting that the dancer use a similar combo system like the monk, but based on kicking, each skill representating a "dance's step" and instead to get a personal buff like the monk, do a buff around her, motivating people or debuffing enemy. but i digress, we are talking about a theory about the monk based on the trailer.
i will simply say this, no point to show 2 monk sparing, especially if this two monk don't use the same combat style. the man (wol) is clearly a monk, the girl on the other hand... nope, this is not a monk.
the stop of the support of the ps3 will not result in more cash invested into 1-2 class, yoshida was clear, if they give something special to one class, they will give something special to every class!
ps: something i want to make quite clear, because some people seems to forget it time to time:
when i talk of Monk i'm talk of Monk in Final Fantasy 14. you can come and say, in the 4-3-6-10 they do this.... no point, we are in Final Fantasy 14 and the monk have already an identity really clear.
