Plot transfer from alts

So I know the reason that we can’t transfer plots between alts is because it’s very easy to start a new character and grind out a few levels quickly rinse and repeat.

But what if plots were only transferable once an alt reached level 50? I could see this still being spammed somehow but not nearly as easy as if they are transferable at any time.

So, what if we have to wait until we got ALL the easy levels?
