Nope. In recent iterations of AC there are two major directions:
* Refinement of current gameplay & skills
* New helpful side-features
There are admittedly some flaws that affects AC's gameplay as whole. For example, annoyingly long grinding time. Those issues and other bugs are worth tackling first.
There are also lots of skills that can be refined to be significantly better, I have a few ideas already. (Vector Reflection could use some better VFXs)
And last, almost everyone in the dev team think that adding some side-features like medicine and ability-related boss fights would be a lot more fun than another new category. So yeah, side cool new features is the direction we want to take next.
