Tooltip DPT Login inaccuracy
Passive tree main stats are not reflected in any of the top right skill tooptips when logging in until any type of stat change occurs (Changing gear, resetting passive tree, etc). It definitely effects MainStat (Str,Dex,Int). I did not test Spell Crit multiplier. (Crit chance currently has its own DPT tooltip bug, see #707 (closed))
Logging in with Vitality nodes selected does not result in any HP fluctuation. Also, mob damage numbers do not change. Both help to confirm it is a tooltip issue, not an actual stat loss.
