I havent really had more then a minute or two to play this week, and havent really taken a close look. But i do know that with the redo on the character development tab all your previous choices were undone(and some of them no longer exist). Make sure you redo your 9 racial traditions and 8 grandmaster trainings(though only the last 1 or 2 of these are likely to matter) and to examine and select your 10 new focus effects. I also remember reading about some gear with specific adorns becoming unattuned, so make sure all your stuff is on. If doing these things plus recasting your buffs doesnt do it, its possible that the new math for hp changed your total(i would guess in the old development tab you had chosen the hit point option rather then the mana or the regen ones at every available level - almost everyone did and the fact that everyone had the same choices is why they redid the focus effects). Hope this helps and best of luck.
