1,Always I think,why the Sorcerer and Alchemist have the vulnerable immune Ability,
I want the all the cast have the vulnerable immune Ability,
Now, we are the Legendary caster,but cant vulnerable immune?
for example,the Legendary can give us the vulnerable immune Ability for some spells and more spell(which like the wizard add the Inflict Critical Wounds, Mass, in his spell book,and more other negative spells)

2, the melee class can heal him self at epic or Legendary levels, I saw the Figher can use the Ability heal him self in U57,but that not enough,I think you can make it be a Ability without the use time,and have a good CD.
For example,it can be used 2min once ,and 1min 30 sec at level 4,can have twice at level 8.and more less CD in other levels and not only for Figher, it's can use for other class which cant cast any spells

Wish you can read this, thanks
