The new 'enhancement system' is an absolute nightmare. Now, whether or not it is working for other classes is unknown to me, because I play primarily a sorcerer, and one that makes good use of the Shiradi system. Some of the things I seem to be unable to find:
Sorcerer 20% damage Capstone (Used by Everyone)
Kinetic Spellcasting line for Force Spells (Used by Shiradi)
Deadly Kinetic line for Force Spells (Used by Shiradi)
Force Manipulation line for Force Spells (Used by Shiradi)
Sorcerer Energy of the Dragonblooded for Spell Points (Used by... EVERYONE)
Repair Manipulation line for Repair Spells (Used by WF Casters)
Also some personal Issues I seem to be having is the loss of approximately 100 Spell Points. This would be made up with the reintroduction of the Dragonblooded line. I also seem to be missing just a few Hit Points, not sure where those went (yes I still took the racial toughness things).
And as far as Shiradi sorcs are concerned, we just got screwed. A huge hit in Force Power (about 50 for me, so 50% less damage right off the bat), no more Force Crit chance lines, and no more deadly force lines for those nice numbers.
The old enhancement system was so much more versatile in my opinion, as there really is no more room in the trees to add in some of the enhancements we lost. I would suggest spending some time to make a Force Savant to give us Shiradis back some damage. As it was, Shiradi wasn't extremely powerful when compared to good nukers using Draconic Incarnation and now its just ridiculous.
Any others having trouble? I seem to think that this was the Multiclass Update, and that pures were screwed.
