As I was reading the Captain bound to ship type thread. I realized what I was really interest in was the part from the "Ask Cryptic" about dividing space and ground skill tree into separate trees. I think that is a great idea! I believe one of the reasons ground gets such a bad review is people aren't spec into at all. Further the first couple times they are exposed to Ground combat they have very minimal idea of what to do, and very few tools to effect it with; Given that they are using what are clearly the worst kits in the game.
So break out the trees so there is not a competition for points and help people realized with a little work ground can be a whole lot of fun!
After giving it more thought this would be a great way to add more skill points without messing with the over all level cap. In effect adding a ground skill point system, you could allow players to accumulate a separate pool of skill solo linked to ground missions. This could add more life to current level cap as well as all future level caps.
Also another cool thing might be to add traits for maxing out a ground skill group. Similar to the way you can add training skills. So if you max out Soldier you gain the Soldier Ground trait, martial arts adds warrior, asto-physics adds astro-physicist etc.
Certainly an interesting idea, and I'd love to see some detailed suggestions. However, if/when they add the ranks of Admiral and Fleet Admiral, the skill point cap will likely go up. Even now, it's possible to have a good build in both areas. With a boosted skill cap, you could have an even better well-rounded build, so I'm not entirely sure a split is needed.
I won't discount this as a good idea. BUT you can easily spec into ground and space if you spend your skill points efficiently and wisely. I think the problem is more with the kits. You are forced into 4 abilities that may or may not allow you to streamline your build. If we could pick our 4 kit powers, we could use ones that use more of the same skills and efficiently spec into ground better.
