It would be nice if when putting towards skill or morphing them that you could take them for a 'test drive' of sorts. That or a video of the skill in use. I upgraded my bow ability 'Scatter Shot' to the one that does more damage and knocks you back. I loved the extra damage, but found the knock back so disorienting and hated it SO much, especially with groups of people all together that I spent 8000g just to a complete respec to get rid of that one morph.
Maybe a 10 min timer to try out the new skill to see if you like it and asked after 10 minutes if you want to keep it or not. If you don't, no biggie, just go put the point in something else instead of having to do a complete respec.
Just a humble thought.
