I think the new talents are a big improvement over the previous ones.
And i hope more will be added before the release. They are all relatively small numerical improvements so i think this can be done. Theoretically.
I also agree with the posters above who argue that investing into specialized builds and therefore increasing attributes to high levels should have its own rewards. Such as were mentioned.
- Reducing the AP cost of lower level abilities and or spells, and skills. (but only lower level ones)
- Reducing cooldowns of the same lower starting skills, spells and abilities.
- Increasing damage (though this has to be done sparingly and carefully since higher level abilities spells and skills would loose their prestige and usefulness otherwise)
All these seem like a very reasonable way to enhance the system a bit more.
But, for all of these, special care has to be taken not to overdo it, - of course.
