you nailed the bad that's for sure
it only flows so well because they made it so basic that a squirrel could probably figure it out

scrap the entire thing
reaper is so incredibly boring
it doesn't even feel like a reaper

where's the necromancy ffs
besides the pet there is no sense of theme in this class

imo:
-should have been a pet class
-selfish dps
-arcane circle ? delete or make it a self buff like RoF but pet goes berserk
-rotation between bursts needs some spice to it, needs less of a burst phase and more of a consistent damage output so that the point above could be more useful
