Nilbus got the point. If anything, the requirement to upgrade will be easy and relaxing. It's meant to be a bonus, an extra fun factor being able to upgrade the donor items and definitely not a punishment or extra hard requirement. Donor or non-donor, the low end content is easy enough and it's super easy to trivialize with items, pets or a few hours of power leveling (then twinking with items and spells).
So again, there's nothing to get worried about here. We can brainstorm, discuss and we can do whatever the community and the DEVs feel right and fun.
