What I'd really like to see is splitting sword specialization into two groups. Then I could actually play a Conan char, haw. Two hand, and the more refined one which we have now.

And another.. Allow people who have perfected a skill/spell to teach 'practice' other people of the same guild. The cost I guess could be slightly higher, and the 'teachers' would have to be like lev 40+, or limited somehow.
