Part of the end game in Shadowlands is a zone called The Maw. For old school gamers this is a step back in time but with a modern spin. No mounts, death penalty is heavy, game play is changing but you know your playing a modern MMO by the fun things you face.
As an example, you progress your daily grind in The Maw, you have a scaling debuff. Starts out small with random swirls under you randomly that cause damage. So as you fights mobs it adds a slight challenge.
Soon you have NPCs swooping out of the sky trying to carry you as high as they can as you fight to kill them, so they try to drop you to your death.
It's PvE that has you on the edge of your seat, much how I feel while PvPing. This is a welcomed part of my daily WoW gaming session. It's just one small part of how Blizzard has gotten it right with the Shadowlands expansion.
This has this old school gamer, very happy and excited.
