How to fix the "buffed" Guillotine
Bring back the old SP3.
Change Bleed chance from 35% back to 50%.
Get rid of Soul Link. SP1 nullifies buffs and puts a Fate Seal Debuff for 8 seconds.
Maybe instead of this passive 2% regen off all attacks, regenerate a much higher % of all damage you receive and inflict from just damage over time effects. This would allow her to heal from suicides as well as attacking without being broken.
That should addesss the main problems.
Extra suggestions
Move ruptures to her base kit with the same chance and potency as the bleeds.
New Sig Ability : Every bleed/rupture has a x% of being a critical bleed/rupture (so that we don't have to bring Purgatory)
New Purgatory synergy : Fate Seal is now a passive and unaffected by Ability Accuracy Reduction.
