SUGGESTION - rare MAPS on atlas + 10 level

I think it would be great to implant some very challenging, rare and rewarding + 10 level maps on the atlas. A kind of do or die kind of situation. So it would challenge players to look for them, gear up and hopefully gain a massive XP BOOST or wipe trying.

Being limited at lvl 82 max for me it's very frustrating at level 95 +

Thoughts?
