I don't really get why so many people consider sch so superior over whm for Twintania, I typically parse about equal to my Sch partner's healing combined with EoS and that's without regen being taken into account. As far as death sentence goes, I can typically get a full strength stoneskin up for it and then time a cure II to land between the death sentence hit itself and the infirmity debuff. That merrily counters lustrate not being affected by the healing debuff. Add in a solid debuff rotation and it's really not an issue.
