Is there anything in particular thst you like, or is it just everything together?
However, it's extremely over powered.
Making a hero 30% vulnerable, or healing yourself for 20% max health per second is insane.
You need to take those numbers down to 1%.
And make the healing per hit, not per second.
Also don't let basic abilities add stacks, and stacks should reset if you switch between dmg/heal.
The Q and W abilities are very generic and boring.
I know that those are her original skills from D2, but maybe you should re-think them to make them more interesting and fun.
The E ability is a bit too much. 1.5 second stun is crazy.
The first heroic is very very OP.
You basically can make the entire enemy team take 30% more damage, that's insane.
In my opinion, you should make it apply to only 1 target, and maybe reduce the cooldown so it won't be too weak as well.
There are some over powered talents like Pleasure In Pain (super OP), Eternal Torment (3 sec stun = dead hero), Shared Pain, and all the lvl 20 talents.
Overall I really like the idea of this hero/trait, but I think you should refine it a bit more.
Turn in down a notch, and get rid of boring/generic abilities.
Cheers :)
I think Piercing Agony might do a bit too much damage; It can, assuming level 1 stats, one-shot most all of the supports/assassins/specialists. Sure, it would scale slower, but it's still a bit high. Some other tuning might be needed here & there, but it looks good to me besides that.
However, I do think I've found a talent build I'd usually take:
Pleasure in Pain, Abundant Anquish, Writhe in Agony, Maiden of Anguish, The Fun's Not Over Yet/Always a Victim, Shared Pain, and Feast of Suffering/Blood Frenzy.
Auto Attack Build that can dish out immense damage or heal for incredibly high amounts of health per second.
