Reaper mode is not the problem. Never has been.
You could give a new player 100 reaper points, their pick of any ten past lives, and automatic level 20 upon the creation of their first toon on a given server. Let's assume they level from 20 to 32 in a month. They're still going to be a newbie who knows jack and poo about the intricacies of the game.
Those 100 reaper points and ten past lives would be like putting a brand new driver's ed student in a base model Honda Civic with racing slicks. Throw the student driver onto a race track and in the end it's still going to be a slow Honda Civic with poor lap times.
Have a veteran player create a brand new toon and give them the same 100 reaper points and 10 PLs. They'll be level 32 and rolling in R10 groups in a week or two depending on luck with gear farming. That's like putting a professional driver into a race car running standard all-season street tires. They'll be a little slower than they would with racing slicks, but they'll still lap the Honda Civic repeatedly.
The learning curve to this game is massive and unnecessarily complex and continues to get worse every time SSG introduces some new system, mechanic, effect, etc. that they pile on top of the existing mess. That's the core problem facing new players.
Simplifying the learning curve is the only thing that will make DDO more newbie friendly.
