No level sync, yes stats sync

Its a better experience than having everything stripped away and spamming 1 for 20 minutes.

That's your choice to enter into lower level content. If you don't like having your abilities stripped away, stick to level cap content. Problem solved.

I mean, the answer is actually pretty simple. You don't scale down. You scale up. Every piece of content should be max expansion level (yes, making everything be "lvl 90 dungeon trash mob HP" or "lvl 90 dungeon boss HP" isn't difficult. I believe in our indie developer) and anyone below that just gets a percentage buff echo. Simple and elegant.

I hope you realize that means getting new content even less often than we already do. They would have to rework every single dungeon every expansion for the new level cap.

It's much better to leave the system as is. If you don't want to be scaled down, don't do the low level content. Do level 90 content instead.
