Some things which might be intresting to know:
Will my character be able to jump without the emote?Yes! And slide, climb trees, swim and other stuff like that.
Will map travel stay in the game?Yes.
Will there be henchmen/heroes?There will be companions but they will not count towards any party you join. They'll be like an extension of your character, and if you choose not to take one, your character will be buffed to compensate.
Levels
So are they raising the level cap?Yes, but the final cap hasn't been announced. It could be as high as 100 or even limitless.
Isn't that going to get in the way of me playing with my friends?A side kick system will be used which will bring your armor and power up to that of people you are with.
Am I going to have to endlessly grind to be the most powerful I can be?No. The amount of power you get at higher levels will reduce significantly. At some point you will not get any more powerful by gaining more levels.
Will I be able to travel to Cantha and Elona?The Movement of the World suggests that the transport routes to those continents have been cut off. It is unlikely that you will be able to travel to those continents at the initial release of the game.
