I don't want to give anything away but there has been some discussion on their thinking about how you should be able to explore all skills and how they thought they would allow that. I know RG has mentioned early on he wants players to feel like they don't NEED to have more than one character in the context of being able to explore all skills. I will say though that I'm not at all happy with what they presented as their current thinking on how to go about that.. but the main point is that it remains an important goal to allow players some kind of means to change your skills. So anyone who's worried about that I hope can be put at some ease at least. Skill progression and distribution is one of those topics I will continue to pursue whenever it comes up to try to come up with the best solutions possible and I hope more people join in on those discussions as much as reasonably possible. We won't all agree with the devs or each other but it's something that really needs to be done right.
