Does it feel like there’s a big gap between Light and Midi wounds? Unless hours count (e.g. you’re in a dungeon) you can basically ignore Light wounds completely. Midi wounds, on the other hand, require medical assistance and two Ob 3 tests.
I think we’re experiencing this because we’re playing at a fairly good clip of gameworld time to real time, so light wounds are basically negligible, whereas one player has been suffering from a failed midi recovery for most of the campaign!
