i think anyone should be able to do any level at any level if they are experienced enough, not like it will be done in record timing, and cant forget pushing taking away exp, low levels can kill most mobs, so there will be plenty of exp gone there from pushing, if a raise in exp is to much to ask for, thats fine, LOW should be exactly the same as HIGH, just not same exp rates, i think your asking to change to much imo.
Raid1 being able to start with 2 people though, whats opinion on that? 4 level 221's on low is abit much.
