I love the way reaper gains momentum on trash packs, starting slow and ending up like an unstoppable terminator that sweeps away worthless souls. It fits the job fantasy very well. The skill is also something I like in a single target rotation. We used to have a lot of dots to track and keep up but now almost no job has them or they are baked into a combo. This debuff is close enough and I hope SE doesn't take it away. Plenty of basic 123 combo rotations out there for those who don't like to press separate skills.
