Even though I believe the 25% to not be enough I rather take that than nothing. Having said that using Signet of Suffering with Plague Signet is still broken. Having reworked the grandmaster trait has now made it useless, at least for PvP, cause its just suicide. As soon as you transform all your life force is wasted cause you have no way to manage conditions while in shroud.
Please change it back to what it was.
