Even if it doesn't appeal to you personally zeebee, that doesn't mean the idea doesn't appeal to others, whether it's 'warped' in a way you like or not. Personally, I wouldn't mind the "Harry the Reluctant Hero," the way it is now.
As for what Lord Raine was saying earlier about this essentially filling a role Hi-Power already fills... Despite the authors who were taking part in it, Hi-Power just didn't appeal to me. Mostly because of the time-travel. Time-traveling Harry is almost always hyper-competent, enough so that he usually almost never runs into any enemies who can stand against him on an even keel.
This Harry, if he's done right anyway, isn't going to have too many more advantages than canon Harry did. From what's been discussed so far, it's mostly just going to be an attitude change and everything that changes will come from how he reacts differently than canon Harry did. I'm looking forward to seeing how this turns out.
