I do agree with your sentiment, but I think the issue will always be what is a compromise to the integrity.
That said, I don't think having a restriction to healing would effect casual gamers; I've played a lot of console games (since games in that market seem to be, for the purposes of this discussion, the realm of the casual gamer) that either didn't allow or limited healing in combat situations. In fact I seem to think most action RPGs on consoles used healing over time as their method of operation, but my memory may just be off (it does cheat, you know). I seem to remember the Champions of Norrath games and the Baldur's Gate: Dark Alliance games using healing over time, for example.
the point was to say "hey, i didn't invent the word. don't look at me, Homer."
Yeah I know you didn't invent the word; I was trying for wit and only got half-way there. My apologies.
