Instead of just granting passive health regeneration, I feel vitality should also reduce the durations of CC against the user. This would make it a lot more useful to max, since a lot of endgame dungeons are very heavy in their debuffs they inflict.
For an example, every 5 VIT grants a 1% reduction in CC durations against the user.
Different values for maxed VIT and their % reduction:
30 VIT (6% reduction)
40 VIT (8% reduction)
75 VIT (15% reduction)
