I think that rather than level-sync, it would be nice if there were nice zones 'light' parties could grind in that didn't necessarily require a mage. Because yes, it is currently a little rough to find a lower level healer atm. However, I am also against level sync. I always personally thought it cheapened the exping process. Also, since at least currently you can solo leves for decent sp, be power-leveled quickly and easily to over rank 30 etc. I just don't see an actual need for it atm. There usually are sb/exp parties rank 30+ on my server and it doesn't seem like they are having tank/mage issues when recruiting for them.
