I'd be okay with a hybrid system, kinda like the writer mentioned. New players can start at level 1 and work their way through the new story missions and strikes to max level, buying vendor gear to beef up for the raid(s). Veteran players would start at current difficulty levels and work up to gear for the raid(s), albeit a little slower perhaps... This would allow all players to experience all the content without either having to start over or dealing with power boosts to get you up to par. And allow for varying difficulty levels like Y1 had...
