What scares me about the popularity of this idea is... why people want the game to be EASIER?
I mean, seriously, are you guys having trouble staying alive in the edition which has the most generous (not)dying rules? Are you NOT having fun with the first edition that really gives you always at least one new thing to do every level up if you want?
So why this desperate need for a free boost? Why aren't people who have played the game for 5 years asking for MORE challenges in a MORE difficult adventure? Why the laziness of wanting an EASIER game?
It sounds to me like in 3e where a lot of people were not really playing or buying the game but were only pirating and talking about it online, endlessly complaining the game needs house rules, playing the social subgame of "character builds" for PCs who were never really played at a table, and always talking about "high powered games" with everyone boosted... and pretending that doing so is for "experienced" or "hardcore" players!
No dear... hardcore players need no stinking boost! And need no wimpy "I don't have the right spell, this game is unplayable, let me take a nap and I will have exactly what I need tomorrow".
I tell you what... I play this game with my little children, and I am PROUD of the game sometimes giving them a hard time exactly because they don't have the right tool for the job, so they have to think harder. It's even damn educational, even if (or maybe because) sometimes they FAIL because of that!
So how the hell grown up adults who think they are better than average at this game (let's face it, most of us here do) would want the game to be EASIER now, after 5 years? Or are you all worried that the rest of the world with their lower IQ will not want to play D&D with you because it's still too hard? That would be the only reasonable explanation...
