You might have to introduce some new-player-only quests to fill in some material gaps while leaving us vets untouched.
I love this idea of accelerating most characters after a year's release onto a node, or whatever.
Even vets benefit, and get a chance to fill in gaps in their rosters a bit more easily.
Sure, it'll cost more gear etc, but we'll have more gear from the shards costing less energy.
Well done coming up with a good solution for getting new players going at a more reasonable pace!
