In fact come to think of it, my top-3 wishes for Reaper in order of realistic implementability would be:

1. Make Ingress/Egress auto-chain into the return, as per the OP's post.
2. Considering the limitations on Harvest Moon, buff it slightly: +10y radius, +10 soul gauge, +200 potency, fancier animation of a giaaaaant scythe sweeping through the target area.
3. Make more meaningful gameplay around a negative gauge economy. In an inverse of how resource-based gameplay for MMORPG classes works in other games, (marginally) unreliable expense via certain procs adding cost (but also potency) to things, thereby always starving us, a fitting element for a job called a Reaper. But the overall damage goes up the more starved we are, kinda.
