Hi, this is Yoshida, the producer/director.
Thank you for the discussion!
I’m sorry about any confusion that was caused due to my lack of input.
Regarding implementing the ability to move freely on the same level as an Assassin's Creed title, we have no plans of actually implementing this from a game design and cost standpoint. However, it would be possible to implement movements similar to other MMOs. For example, in other games it is possible to reach high places by jumping up against the terrain...
We would like to try to implement swimming by adding underwater areas in expansion packs, although this will require adding an incredible number of swimming animations to be created. Features built around the water in EverQuest were very fresh at the time. (Although I drowned so many times… I raised my skills safely at the fountain… Before that, I died so many times by starting as Wood Elf.) I think that underwater temple raids would be fun, so I would like to implement this concept along with the ability to swim.
