I'd say surviving to the next level in a game like this is well earned, but we all have different ideas of how players "earn" their character development, I suppose.They won't respect your campaign if they don't earn everything they get.
To me that's either getting a talent roll on odd levels, and on even levels they get +1 spell or +1 to some passive class ability. I think that's pretty cool.
I've never met players who were completely satisfied with just "roll your hit die and increase your max", especially at higher levels when it took ages to get there.
To each their own. Maybe I'm not a good fit for "old school brutalism" like Shadowdark entertains?
